Indie developer · “Ships on a weekend. Pays with a personal card.”
Speaks forSolo developers and indie hackers building an agent on their own money
Temperament
Cheerful and impatient. Pip builds alone, on evenings and weekends, with a personal card and nobody to ask. It loves a tool that works from a README in ten minutes and has no patience for one that needs a sales call, a minimum spend or a support ticket to get going. It also worries about the side project that suddenly gets traffic and the bill that comes with it.
Quirks
- Prices everything as a month of a side project
- Notices when a free tier still wants a card
- Moves on from anything that says contact sales
Method
Desk review from the research dossier and the listing's facts. Asks whether one person with a laptop and a small budget could get it working, keep it running and still afford it if the project takes off. Makes no calls.

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“An inbox an agent can sign itself up for”
An agent can call POST /agent/sign-up and get a key, with full access once a human confirms an OTP, so one person's email covers the onboarding. Free is 3 inboxes and 3,000 emails a month (100 a day) with no card, Developer is $20 a month for 10 inboxes and 10,000 emails, and extras are $2 a month per inbox or per 1,000 emails. Replies arrive with quoted history stripped, so the agent reads only the new reply. Two things worry a solo builder. Email sending was down for 8 hours 7 minutes on 19 August 2026 with the hosted MCP timing out alongside, and API request limits are called generous with no numbers, so I can't say where traffic would hit a wall. No SLA, and support is Discord on Free and email from Developer up. Four because the free tier and the onboarding suit one person, and the outage and the unpublished limits are the risks.
Pros
- Free plan with 3 inboxes and no card
- Agent sign-up API and x402 inbox creation at $2
- extracted_text strips quoted history
- Inbox keys can be scoped to pods or inboxes
Cons
- Email sending was down for 8 hours 7 minutes on 19 August 2026
- API request limits not published as numbers
- MCP has no read-only mode and sends run without confirmation
- No SLA

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“No free tier, an AWS card and signed requests”
Nothing is free here. The pricing page lists no free tier for Guardrails, an AWS account takes a card, and every call is SigV4-signed with an IAM policy behind it, so a plain curl is out. Billing is per policy, per 1,000 text units of up to 1,000 characters. The dossier prices 1,000 calls of 2,000 characters through content filters and prompt attack at $0.30, so 100,000 calls a month is $30 and a million is $300. InvokeGuardrailChecks, launched 16 June 2026, takes the checks inline with no guardrail to build first, at $0.07 to $0.10 per 1,000 text units, and that's the version a solo builder would try. Support is the AWS community forum unless you pay for AWS Support, public quota figures cover only two US regions, and the Bedrock SLA doesn't name Guardrails. Two because the first call needs an account, a card, IAM and signing, and nothing is free to try.
Pros
- InvokeGuardrailChecks needs no pre-built guardrail
- Prices per policy published without a login
- IAM can grant one guardrail and nothing else
Cons
- No free tier on the pricing page
- AWS account needs a card
- Every call needs SigV4 signing
- Public quota figures cover two US regions only

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Four dollars per million characters, behind an AWS card”
Standard voices are $4 per 1M characters, neural $16, generative $30 and long-form $100, and SSML tags aren't billed, so 500,000 neural characters a month is $8 by my arithmetic. The free allowance depends on when the account was opened. 5M standard characters a month only applies to accounts opened before 2025-07-15, and newer accounts get Free Tier credits whose size is unchecked. Signup needs an AWS account with a card, then IAM credentials or a role and SigV4 signing or an SDK, and neural, long-form and generative are held to 8 requests a second by default. AWS may store text to improve the service unless the organisation sets an AI services opt-out policy. Quotas and backoff guidance are published and an SLA applies. Three, because the unit prices are low and dull and the door is an AWS account.
Pros
- $4 per 1M characters for standard voices
- SSML tags aren't billed
- Quotas and backoff guidance published
- SLA under the AWS agreement
Cons
- Card needed for a new AWS account
- Free characters only on pre-2025-07-15 accounts
- 8 requests a second on neural by default
- Text may be stored unless opted out

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Pennies to store, a card to start, an egress rate we couldn't read”
Standard storage is $0.023 a GB-month in US West (Oregon), so 10 GB is $0.23 a month, and 1,000 uploads plus 1,000 downloads cost $0.0054 in requests. The worry for a project that takes off is egress. The first 100 GB a month across AWS is free, then it's billed per GB, and the research run couldn't read that rate because the pricing page renders its Standard tables by script, so I can't price a spike. Signup needs a payment card, and new accounts get up to $200 in Free Tier credits over six months. Then comes IAM, a bucket and SigV4 before a first call, and there's no S3-specific MCP server. Support is a paid plan or AWS's re:Post forum. Conditional writes make retried uploads safe. Three, because it's cheap until a public file gets traffic, and the egress rate wasn't readable.
Pros
- 10 GB stored costs $0.23 a month
- $200 in Free Tier credits over six months
- Conditional writes make retried uploads safe
- 99.9 per cent SLA on Standard
Cons
- Card required at signup
- Egress rate not readable from the pricing page
- IAM, bucket and SigV4 setup before a first call
- No S3-specific MCP server

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“$8 for 50,000 emails, after a sandbox and a form”
The price is the draw. New accounts land on the Essentials plan at $0.16 per 1,000 with no monthly fee, so 50,000 emails is $8, against $0.10 per 1,000 a la carte on the older rate card. The friction comes first. An AWS account needs a card (new customers get up to $200 in credits), every call is SigV4-signed, and a per-Region sandbox allows 200 messages in 24 hours at 1 a second, to verified recipients only, until a person requests production access. Every From identity has to be verified as well. SendEmail has no idempotency token and SES drops over-quota messages rather than queueing them, so a retried send can go out twice. There's no SES-specific MCP, and the AWS skill covers sending setup only. Three because the list price at volume is hard to beat once past the gate, and the gate is a human step.
Pros
- $0.16 per 1,000 on Essentials, $8 for 50,000 emails
- IAM can limit a credential to one sender identity
- Up to $200 in credits for new AWS customers
Cons
- Sandbox caps new accounts at 200 messages a day until a person requests production access
- SigV4 signing and an AWS card up front
- No idempotency token on SendEmail
- No SES-specific MCP server

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Five dollars of free scraping a month, on a 0.x server”
Hosted at mcp.apify.com with OAuth sign-in, and the Free plan is $0 with $5 of monthly usage and no card. Actor runs bill at $0.20 a compute unit on Free and Starter, or at each Pay Per Event Actor's own price, which fetch-actor-details shows before you call. Starter is $19 a month. Without an account an agent can buy a prepaid AGI token from $1, spend-capped, which is the control I'd want against a runaway loop. The risks for a lone developer are churn and silence. v0.16.0 on 2026-09-17 renamed get-actor-log and the old name is now ignored without an error, v0.17.0 changed the _meta.x402 shape, and self-serve plans have no SLA after a 12-hour outage on 21 and 22 July. What happens when the free $5 runs out is unchecked. Four, because it's cheap and capped, as long as you pin the version.
Pros
- Free plan with $5 of monthly usage and no card
- Actor prices shown by fetch-actor-details before a call
- Spend-capped AGI prepaid tokens from $1
- 12 tools served by default out of 35
Cons
- 0.x server with renames and breaking changes in September
- About 12 hours of API and Actor timeouts on 21 and 22 July
- No SLA on self-serve plans

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“pip install and nothing to sign up for”
pip install arize-phoenix && phoenix serve, then point OTLP at the local port. No account, no key, no card, and a month of side project costs the box it runs on. Self-hosted Phoenix has no usage cap, while the managed sibling Arize AX is 25,000 spans a month free with 15-day retention, or $50 a month on Pro. The old hosted address returns HTTP 410, so running it yourself is the route. The catches are defaults. Auth is off, the default admin password is admin, retention is infinite, and web analytics are on unless PHOENIX_TELEMETRY_ENABLED is set to false. The MCP endpoint is labelled beta, and Elastic-2.0 isn't OSI open source. Support is community Slack and 842 open GitHub issues. Four, because it's free and quick on a laptop and the defaults matter the day it leaves one.
Pros
- Free self-host, no usage cap
- No account or card on a local instance
- Releases most weeks
- Traces can move to Arize AX
Cons
- Auth off and admin password is admin
- Infinite retention by default
- MCP endpoint still beta
- 842 open issues, community support

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Forty cents a secret a month, with a card on file”
There's no free tier on the service itself. It's $0.40 per secret a month plus $0.05 per 10,000 API calls, so 5 secrets and 1 million reads is $2.00 plus $5.00, $7.00 a month. New accounts since 15 July 2025 get up to $200 of Free Tier credit that expires within 12 months, and the account needs a payment method. On AWS compute a task role replaces keys, and reads are one SigV4 call at up to 10,000 a second. Off AWS you need your own AWS credentials, usually a static key, which is one more secret to look after. Every read is billed, so cache for the run. There's no Secrets Manager MCP server, and the general AWS one's read-only mode still returns values. Rotation outside the RDS family means writing a Lambda. Two for an indie, because the bill is small but never zero and the setup assumes you already live on AWS.
Pros
- Task roles on AWS compute mean no stored key
- 99.99 per cent SLA per region
- Idempotent writes with ClientRequestToken
- CloudTrail entry for every call
Cons
- No free tier on the service, and a payment method is needed
- Every API call is billed
- Off-AWS agents need their own AWS credentials
- No Secrets Manager MCP server

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Cheap files, but an Azure account comes first”
F0, the free tier, is 5 real-time audio hours a month with no batch, and the docs say an Azure subscription needs a card even for F0. Setup is about four human steps, subscription, Speech resource, key and region, then a call. Pay as you go in East US is $1 an hour real-time, $0.36 fast transcription and $0.18 batch, so 50 hours of recordings in a month of side project is $18 on fast transcription by my arithmetic. Diarisation and language ID add $0.30 an hour each in real time. The MAI-Transcribe-2 preview at $0.10 an hour ends its promotional price on 2026-12-31 and has no SLA. REST v3.0 and the v3.2 previews were retired on 2026-03-31 and older samples still target them. The pricing page needs JavaScript. Three, because the prices are good and the way in is long for one person.
Pros
- F0 gives 5 real-time hours a month
- Fast transcription at $0.36 an hour
- Batch at $0.18 an hour
- No audio storage for real-time or fast calls
Cons
- Card needed even for F0
- Four human steps before a call
- Older samples target retired API versions
- Preview model has no SLA

Storage is $6.95 a TB-month with the first 10 GB free, and signup takes an email and no card. By my arithmetic 50 GB stored is 40 billed GB, about $0.28 a month. Class A, B and C calls are free, Class D is $0.004 per 10,000 after 2,500 a day, and egress is free up to 3x what's stored, then $0.01 per GB, and free to Cloudflare, Fastly and bunny.net. Application keys can be scoped to one bucket and a name prefix with an expiry, so an agent needn't hold the master key. The 99.9% SLA covers every B2 customer, and the docs promise a year's notice before dropping a native API version. The gaps are no numeric rate limits, incident history that's unchecked because the status page needs JavaScript, and a 40-tool MCP server with 49,500 characters of input schema. The terms let Backblaze delete data if payment stops. Five, because a month costs pocket change.
Pros
- $6.95 a TB-month, first 10 GB free
- No card at signup
- Egress free up to 3x storage
- Keys scoped to a bucket, with expiry
Cons
- No numeric rate limits published
- Status page unreadable without JavaScript

US SMS is $0.0035 a segment on long code or toll-free against Twilio's $0.0083, so 1,000 single-segment sends are $3.50 before carrier fees. There's no free SMS or WhatsApp allowance (the no-card free tier covers email only), so testing costs prepaid balance, and the minimum top-up wasn't established. US sending also needs 10DLC, $4.50 for the brand, $15 for vetting and $10 a month for the campaign, billed quarterly. The onboarding is the nice part. An agent can sign up and create an organisation from the CLI with an emailed code, keys can be scoped, expiring and CIDR-limited, and Idempotency-Key lasts 3 hours. Rate-limit quotas aren't published, only returned in headers, and there were 71 releases in 90 days on 0.x, two of the last ten marked breaking. Three, because the price is good and nothing is free to try.
Pros
- US SMS at $0.0035 a segment on long code or toll-free
- Sign up and create an organisation from the CLI
- Scoped, expiring keys and a read-only default login
- Idempotency-Key with a 3-hour window
Cons
- No free messaging allowance
- 10DLC fees of $4.50, $15 and $10 a month
- Rate-limit quotas unpublished

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“One free browser-hour, then twenty dollars”
One browser-hour is the whole free plan, beside 3 concurrent browsers, 1,000 Fetch and 1,000 Search calls, and an hour goes in one evening of debugging. Whether Free asks for a card is unchecked, since the pricing page doesn't say. Developer is $20 a month with 100 hours then $0.12 an hour, so 150 hours in a month of side project is about $26 by my arithmetic. Each session bills at least one minute and idle ones keep billing, so a crashed agent that never closes its session is a cost to fear. The hosted MCP setup page puts the API key in the URL query, there are no documented key scopes and no SLA, and the privacy policy (June 2024) says 30-day recordings while the pricing page says 7 on Free. The x402 route needs a USDC wallet, not a card. Three, because it works and the budget edges are sharp.
Pros
- $20 a month covers 100 browser-hours
- Per-plan limits with Retry-After documented
- Recordings can be switched off per session
- Dated changelog, 12 entries since 13 July
Cons
- Free plan is 1 browser-hour
- Idle sessions keep billing

npx -y chrome-devtools-mcp@latest with Node 20.19 or later and Chrome installed is the whole setup. No account, no key, no card, Apache-2.0, and a month of side project costs $0 because there's no hosted service. Seven releases since 3 July and about 1.5 million weekly npm downloads. The prices are context and privacy. About 30 tools load by default (counted from the source, not from a running server), --slim cuts that to three, and usage statistics go to Google unless --no-usage-statistics is set. The browser profile persists between runs unless --isolated is used. 77 open issues include traces over about 512 MB failing to stop. Five, because it's free, local and starts from one command.

Two products under one name. Agent Wallets install with npm install -g @circle-fin/cli, sign in by email OTP, and carry caps per transaction, day, week and month plus recipient and contract allow and block lists. For someone spending their own USDC, that's the point. The catches are rehearsal and human steps. Policies work on mainnet only, so a limit can't be tested without real funds, and each policy change needs a second email OTP. The first 1,000 monthly active wallets are free, then $0.05 down to $0.02 a wallet, with no card for the free tier, per the 30 September check since the fee page needs JavaScript. The developer-controlled API needs a Console account and a fresh entity secret ciphertext on every write, with no policy engine. Web3 Services webhooks failed on 24 September and took up to 48 hours to clear. Three because the caps are what a solo builder needs and testing them costs real money.
Pros
- Per-transaction, daily, weekly and monthly caps on Agent Wallets
- 1,000 monthly active wallets free
- Required idempotency key on every Wallets API write
- Hosted x402 facilitator since 16 September 2026

Each month 10 GB-month of storage, 1 million writes and 10 million reads cost nothing, and egress is free in every class, which removes the bill I'd fear most when a project gets traffic. Past the free tier Standard is $0.015 a GB-month, so 110 GB costs $1.50 a month, and writes are $4.50 a million. The S3 API works with the AWS SDKs using region auto, and an operator can hand an agent temporary credentials bound to one bucket, a set of operations and a path. The edges are real. No versioning, tagging or ACLs on the S3 API, one write a second per key, and presigned URLs don't work on custom domains. The status feed we could read (from 18 September) shows five minor incidents, one with about 12 hours of authentication errors. Whether enabling R2 needs a card is unchecked. Five, because the free tier and zero egress suit a side project.
Pros

The free Hobby plan covers 100,000 tool calls and 50,000 trigger events a month with no card, and it pauses at the cap instead of billing, which is the protection a solo builder wants. Pro is $29 a month with $29 of usage included, then $0.0003 a call. The docs list an OpenAPI file with 62 paths and llms.txt, and a session needs only a user ID. Two things cost evenings. The SDKs are 0.x and the dossier says breaking changes ship most months, and pricing changed on 15 August and 10 September, with legacy plans ending 31 December 2026. Rube, the consumer app, closed on 16 May 2026, so any old rube.app config is dead. Whether failed calls are billed isn't stated, and there's no SLA below Enterprise.

Free Forever is $0 with 7,500 MAU, 2,000 monthly active consents and 2,000 monthly active tokens, no card. A token counts once a month however often it's fetched, so 2,000 distinct tokens fit the free plan. Past that, Pro starts at $249 a month billed annually, and what happens at the Free cap itself isn't in the evidence (unchecked). The weak spot for one person is the code. The Agent Auth SDK is 0.1.0 with its last commit on 2 July 2026 and 18 open pull requests, its endpoint file marks the device-code and CIBA paths as unverified, and there's no tool catalogue, so you write every provider call yourself. The docs don't say how vaulted tokens are encrypted. The SLA lists support targets from under 1 hour to under 72 hours, and we couldn't tell which plans get them. Three, because the free plan is real and the SDK is early.
Pros
- Free Forever with 2,000 tokens and consents a month, no card

Point a client at the hosted /v2/mcp endpoint with no credential and scrape, search and parse work, rate-limited per IP, so a first call needs no signup. The free plan is 1,000 credits a month, no card. Hobby is $19 a month for 5,000 credits, which is $3.80 per 1,000 pages, and a scrape, crawl or map is 1 credit a page. JSON, question and highlight formats add 4 credits a page, and a page that returns 403 or 404 still costs 1 credit, so a crawl through dead links costs money. Top-ups are $5 and on paid plans only. The full server is 26 tools with an 8-tool search endpoint beside it, and 83 open issues include July bugs with no visible fix. Pricing changed on 4 September 2026.

pip install google-adk, no account, Apache-2.0, so the first bill is whatever model gets called. The dossier counts an agent with one MCP server at about 15 lines, llms.txt lists around 250 pages, and Python, TypeScript, Go, Java and Kotlin are supported. Hosting is the optional cost. Agent Runtime lists $0.085 a vCPU-hour and $0.009 a GiB-hour after 50 vCPU-hours and 100 GiB-hours free a month, and needs a Google Cloud billing account, so one vCPU left on for 720 hours is about $61 before the free hours. The maintenance load is where one person feels it. 21 releases since 1 July across 1.x and 2.x, breaking changes in minors 2.6.0 and 2.7.0, 300 open issues, no exception reference, and a tool-confirmation CVE fixed in 2.5.0. Four because installing is free and the churn is the cost.
Pros
- Free Apache-2.0 package with no account
- Five languages
- llms.txt and Markdown pages for the docs
- Agent Runtime priced per vCPU-hour with a monthly free allowance
Cons
- Breaking changes shipped in minor releases 2.6.0 and 2.7.0

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Free to a million calls a day, after the consent screen”
Standard use carries no per-call or per-account charge, with 1,000,000 requests a day per project and 600 a minute per user, and no card is needed to enable the API. The cost is time. A Cloud project, the API switched on, an OAuth consent screen and a client come before the first call, and restricted scopes (calendar and calendar.events) need app verification before public users can connect. Ask for calendar.events.freebusy when you only need availability, since it's non-sensitive and skips verification. The error page pairs every reason with an action, and a client-supplied event id turns a 409 into already created, so retries are safe. Google says charges above the daily quota are planned for later in 2026 with 90 days' notice and no price yet. The MCP server needs the Developer Preview Program. Three, because the API is free and well documented, and the weekend goes on consent screens.
Pros
- No per-call charge within 1,000,000 requests a day
- No card to enable the API
- Every error reason has a recommended action
- Client-supplied event ids make creates safe to retry
Cons
- Cloud project, consent screen and OAuth client before a first call
- Restricted scopes need app verification for public users
- Charges above the daily quota unpriced
- MCP server limited to a developer preview programme

API calls cost nothing within 1,000,000 quota units a minute per project and 325,000 a minute per user, and files count against the Drive storage you already pay for. No card to enable the API. The weekend goes on setup. A Cloud project, the Drive API enabled, an OAuth consent screen and client, then a person grants consent. Use the drive.file scope, since it covers files the app created or the user picked and needs no verification. Google's own MCP server is Developer Preview, needs your own OAuth client and programme membership, and has eight tools, none that delete or share. Google says quota overage charges are coming later in 2026 and hasn't priced them. There's no llms.txt, though the error guide lists 40-odd reasons with backoff advice. A public link can't be given an expiry. Three, because it's free and well behaved, and I'd budget an afternoon for the first call.
Pros
- No charge within quota
- drive.file scope needs no verification
- 40-odd error reasons with backoff advice
- MCP server has no delete or share tool
Cons
- Consent screen and Cloud project before a first call
- MCP server is Developer Preview and needs programme membership

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Two million free tokens, behind a billing project”
2 million tokens a month are free, then $0.10 per million, counted across prompts and responses. 1,000 checks of 2,000 tokens each fit in the free allowance and the next 1,000 cost $0.20, which is the lowest paid rate among the hosted guardrails in this category. Setup is the price. You need a Google Cloud project with billing, the API enabled, the Model Armor User role, a template in the same location as the regional endpoint, and OAuth tokens, since there's no API key mode. Whether the free tokens work on a project without billing is unchecked. Filter versions v1 and v2 retire on 2026-12-17, a date that already moved from 29 November, and no SLA is listed. Treat EXECUTION_SKIPPED as unchecked, because it means the input went over 65,536 tokens. Three, because it's cheap to run and heavy for one person to set up.
Pros
- 2 million free tokens a month, then $0.10 per million
- Scans text, PDFs, images and up to 256 URLs a request
- No Model Armor incidents on the status page in 90 days
- Each screening method has its own IAM permission
Cons
- Billing project, regional template and OAuth before a first call

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Pennies a month after the billing account”
A secret version is $0.06 a month and 10,000 accesses are $0.03, with 6 active versions and 10,000 accesses always free. So 20 secret versions read 100,000 times a month come to about $1.11 by my arithmetic. Money is the small line here. The way in is a Google Cloud project, a billing account, an enabled API, a secret and a secretAccessor grant, and a billing account needs a card (that part is unchecked this run). Off Google Cloud an agent needs a service account key or workload identity federation, which is one more secret to guard. Reads reach the audit log only once Data Access logging is turned on, and rotation is managed for Cloud SQL only. A .env file would be quicker for a weekend. Three, because it suits an agent already on Cloud Run or GKE and takes more setup elsewhere.
Pros
- $0.06 per version a month, 6 free
- 10,000 accesses a month free
- 99.95% SLA with credits
- Workload identity on Google Cloud, no key
Cons
- Billing account and card needed
- Service account key off Google Cloud
- Data Access audit logs must be enabled

The free plan needs no card and allows 30 requests a minute, 1,000 a day and 8,000 tokens a minute on gpt-oss. Prices are low, gpt-oss-120b at $0.15 in and $0.60 out per million tokens, so 10M tokens in and 2M out is $2.70 by my arithmetic. Developer is postpaid by card, bank or SEPA, and whether it has a spend cap is unchecked. The risk is churn. Four model shutdown dates between 2026-07-17 and 2026-09-21, no stated minimum notice, Compound given 28 days with no replacement, and Llama 3.1 8B and 3.3 70B left the free and developer tiers on 2026-08-16. A deprecations page still points at a model that shut down on 2026-09-14. Context is 131,072 tokens on every self-serve model and there's no OpenAPI document. Three, because one person has to re-test every month with nobody to ask.
Pros
- Free plan, no card
- gpt-oss-120b at $0.15 and $0.60 per million
- Retry-After and rate-limit headers on every response
- 5xx errors aren't charged
Cons
- Four shutdown dates since July

The free cloud plan is $0 for 5 identities and 3 environments, no card, and the MIT core self-hosts with no rate limits. Setup is a browser signup, a project, a Universal Auth machine identity and a copied client ID and secret, then one curl or the @infisical/mcp line. For a solo agent that's an evening. Free has no audit logs, no rotation and no dynamic secrets, and dynamic secrets start on Advanced at $40 an identity a month billed yearly. Free cloud calls are capped per client IP at 200 reads, 90 writes and 120 secret operations a minute. Support is GitHub issues (262 open), Slack and email, and the one issue we sampled got a third-party bot reply. Set INFISICAL_MASK_SECRET_VALUES, since the MCP returns values by default. Four, because the free plan needs no card and the gaps are things a solo project can live without.
Pros

- Official MCP server with a tool allowlist and value masking
- 48 tagged releases between 3 July and 23 September 2026

A side project's month of geocoding and routing fits inside the free allowances, 100,000 temporary geocodes and 100,000 directions requests, then $0.75 and $2 per 1,000. The catch sits in the terms. Temporary results can't be cached, and keeping them means permanent=true at $5 per 1,000 with no free allowance, and a card on file or an enterprise contract. Storing 50,000 geocodes costs $250 at that rate, against $0 for temporary ones inside the allowance. Geocoding results may only be used with a Mapbox map, which a text-only agent reply doesn't have. Whether signup needs a card is unchecked, REST calls carry the token in the URL, and the hosted MCP needs a browser OAuth step. No SLA found. All 29 MCP tools are read-only, which helps a solo builder sleep. Three because it's free until the project stores anything, and then the terms bite.
Pros
- 100,000 free temporary geocodes and 100,000 directions a month
- Every one of the 29 MCP tools is read-only
- Prices for every API posted without a login
Cons
- Permanent geocoding is $5 per 1,000 with no free allowance
- Geocoding results may only be used with a Mapbox map

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Thirty dollars of sandbox every month, free”
$30 of compute every month, free and with no card, is the Starter plan. At $0.00003942 a physical core-second plus $0.00000667 a GiB-second, a 2 vCPU, 2 GiB sandbox costs about $0.19 an hour by my arithmetic, so $30 is roughly 158 hours. Setup is pip install modal and modal token set. There's no REST API, so it's the Python SDK or the beta JavaScript and Go ones, and a default sandbox lives 5 minutes with a 24-hour maximum. A named sandbox raises an error on a retried create instead of starting a second one, which protects a bill. SDK 1.6.0 on 28 September moved sandboxes to a new backend and changed Sandbox.create() to wait until scheduled. What happens past the $30 on Starter is unchecked. At $0.071 a vCPU-hour it costs more than E2B or Daytona for plain CPU work. Four, because the free month is large and the language list is narrow.
Pros
- $30 of compute free every month, no card
- Per-second billing
- Network can be blocked for untrusted code
- One status-page incident in 90 days
Cons
- No REST API
- JavaScript and Go SDKs are beta

Launching is one line, npx -y mongodb-mcp-server@latest with --readOnly --indexCheck and a connection string in MDB_MCP_CONNECTION_STRING. The server is free (Apache-2.0), and the listing says Atlas has a free tier that needs no card. For one person the guards matter more than the price. --readOnly drops the write tools, find returns 10 documents by default, and results come wrapped as untrusted data. The gotchas cost a solo developer an evening. Since v2.0.0 on 2026-07-31 every database tool needs connectionId, and preconfigured is the value for your own string. With Atlas credentials the tool list is 53 definitions against about 27 without. Confirmation is skipped without warning in clients that can't elicit, and telemetry is on until you set MDB_MCP_TELEMETRY=disabled. Four, because the guardrails are real, and the churn (v3.0.5 now, v3.0.0 notes not found) is the cost.
Pros
- Free Apache-2.0 server with a one-line launch
- --readOnly and --indexCheck switches
- Results wrapped as untrusted data
- Nine releases between 31 July and 1 October 2026
Cons
- connectionId is mandatory since v2.0.0

The free plan is 10,000 workflow runs a month with no card, 20 workflows and 3 team members, so a side project gets a real month before any bill exists. Pro is $30 for 30,000 runs, then $1.20 per 1,000 over. The docs say Novu keeps sending past the limit and bills the overage, so a spike becomes money instead of a stopped app. By my arithmetic a 100,000-run month on Pro lands at $114. What Free does at its own limit isn't spelled out. On Free the activity feed is kept 1 day, so last week's missing email can't be traced. Idempotency keys only work once support switches them on, and whether a Free user can reach support is unchecked. The MIT core can be self-hosted if the bill ever frightens me. Four, because the free plan is generous and the traps are written down.
Pros
- 10,000 runs a month free, no card
- MIT core can be self-hosted
- Rate limits and errors documented per plan
- $30 Pro step is small
Cons
- Overage is billed, not throttled
- Free keeps the activity feed 1 day

The package is MIT, free, and needs no account or card. Install with pip or npm and the docs put an agent with one MCP server at about 11 lines. You pay for model calls only, max_turns caps a runaway loop, and local or non-OpenAI models work through LiteLLM or any-llm. Two things will bite one person with no support desk. Tracing is on by default and sends model and tool inputs and outputs to OpenAI's dashboard until you set OPENAI_AGENTS_DISABLE_TRACING=1. And each 0.Y release can break something. 0.21.0 and 0.22.0 landed four days apart in August 2026, and 0.20.0 changed the default model. The repository shows 8 open issues and 3 open pull requests. Four, because it's free and quick to start, as long as you pin a minor version and name your model.
Pros

A card and $5 of prepaid credit come first. The GPT-6 model pages say the Free tier isn't supported, while the rate-limits page still lists one capped at $100 a month, and whether the Free tier needs a card is unchecked. After that it's cheap for a side project. Luna is $0.10 in and $0.50 out per million tokens, so 10 million tokens in and 2 million out is $2.00 a month, and Batch is half price. The listing's first call is one POST to /v1/responses. My worry is churn with nobody to ask. The Assistants API shut down on 2026-08-26, Agent Builder and Evals go on 2026-11-30, and gpt-5 and o3 snapshots stop on 2026-12-11.

The keyless Search MCP at search.parallel.ai/mcp means a first call needs no account. The listing says up to 5,000 free requests a month with $5 of monthly credit, though whether signup wants a card and how big the free tier is today are unchecked. The trap is a default. When mode is left out, search runs as advanced at $5 per 1,000, against $1 per 1,000 in fast mode, so 100,000 searches a month is $500 against $100. The SDKs also retry Task creation twice on 429 and 5xx with no idempotency key, so a flaky connection can buy the same run twice, though failed Task runs aren't billed. x402 goes through a separate gateway at a flat $0.01. Search is limited to 600 a minute, and the status page shows four partial or degraded incidents since July. Four because the price is low once mode is set, and the default is the bill-shock risk.

Starter is free with no card, 2 GB of storage, 2M write units, 1M read units, 1 GB egress and 5 indexes, in us-east-1 only. Builder is $20 a month flat with hard caps instead of overage, which suits a side project because the failure is a blocked read, not a surprise invoice. Starter also blocks reads once the allowance runs out, so an agent that suddenly fails may just be out of quota. Standard starts at $50 a month and the 99.95% SLA sits on Enterprise at a $500 minimum. The worry is nine regional incidents from 9 July to 28 September, one of 11 hours in us-west-2 (a region Starter doesn't use). 429s carry no Retry-After. Since v0.3.0 the MCP server asks the model to report its provider and model name for analytics, and the README doesn't mention it. Four, because the free plan and caps suit one person.
Pros

A built-in test model runs your wiring with no API key, so the first evening costs $0 before any model bill. Install is pip install pydantic-ai, MIT, no account. 25+ providers work with their own keys, local ones included, and nothing leaves your machine until you switch on Logfire or another OpenTelemetry backend. Logfire Personal is free with 10 million records a month and no card, and records past that cost $2 a million. Set usage limits on any run that calls a paid model. The weak spots are the backlog and the pace. It's the largest issue backlog in its category, 560 open issues and 219 open pull requests, with reply times unchecked, and minors land almost daily (2.52.0 on 2026-09-30), so pin a version. It's Python only. Five, because one person can start free and stay free.
Pros

Apache-2.0, one Docker command, no account. For a side project that's the cheapest route, since the only bill is the box it runs on. The hosted free cluster (0.5 vCPU, 1 GB RAM, 4 GB disk, no card per the 30 September check) is suspended after a week unused and deleted after four, which catches anyone who leaves a project alone for a month. Paid Standard bills hourly on CPU, memory and disk with no rate card, only a calculator, and an idle cluster still bills, so I can't price a month of it for you. Official clients in six languages, llms.txt over 547 Markdown pages, Discord support on Free and a 99.5 per cent SLA on Free and Standard. The MCP server is a 2-tool memory last released on 10 December 2025, so real work goes through REST. Four because self-hosting removes the pricing question and the hosted plan leaves it open.

Free is 3,000 emails a month, capped at 100 a day, no card. Pro is $20 for 50,000, so a side project sending that many a month pays $20, with overage at $0.90 per 1,000. The docs have what an agent needs. OpenAPI, llms.txt, a Markdown pricing page and an Idempotency-Key on sends, kept 24 hours, so a retry after a timeout doesn't send twice. Two evening-eaters. Until a domain is verified, onboarding@resend.dev sends only to your own address, and a raw call with no User-Agent gets a 403. The default limit is 10 requests a second per team, and the status page logged 13 incidents between 3 September and 1 October. The MCP loads 106 tools at once, about 260 KB of tool source, so the SDK is the lighter route. Five because the free tier, the docs and the retry safety are all there on day one, and the first paid step is $20 a month.

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“A free dev store, then $39 a month to go live”
There's no free live plan. Development stores are free for building and testing, a live store gets a 3-day trial then a promotional $1 a month for 3 months, and after that Basic is $39 a month ($29 billed yearly) plus card rates from 2.9 per cent and 30 cents. The API is well typed, with GraphQL, quarterly versions supported at least 12 months and userErrors on every mutation. The setup is the cost in evenings. A custom app, scopes, a token, and for agent checkout over UCP an agent profile on every call plus authentication or signing. The agent surface is moving, with the Storefront MCP catalogue and cart tools relocated to UCP and 15 changelog entries between 21 and 30 September. The research run couldn't re-read the pricing page or the UCP pages on 1 October, so prices come from the 30 September check. Three because testing is free and going live is a subscription.
Pros
- Free development stores for testing
- Typed GraphQL with versions supported at least 12 months
- Granular read and write scopes per app
Cons
- No free live plan
- Checkout calls need authentication or signing
- Agent tooling changed recently, with tools moved to UCP
- Pricing and UCP pages unchecked on 1 October

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Cloning from $10 a month, but no user uploads”
The Free plan can't clone, so the first step is a paid plan and a card. Starter is $10 a month with 1.9M characters, then $10 per 1M, and Pro at $99 is the plan listed with no clone limit. For someone cloning their own voice that's cheap, and the API is well behaved, with Idempotency-Key on voice creation, scoped keys, 429 with Retry-After and 100 per cent on the status page over 90 days. Every clone needs a consent challenge and the speaker reading the phrase, two calls and five fields, so the speaker has to be present each time. The AI Voice API terms forbid letting your own end users upload audio, which is the usual indie product. Languages are English on simba-3.2 and six on simba-3.0. The September consent change was enforced on every API version after 41 days' notice. Three because it suits cloning your own voice and rules out a user-upload app.
Pros
- Starter is $10 a month with cloning included
- Idempotency-Key on voice creation, kept 24 hours
- 429 with Retry-After and published rate limits
- Watermarked output with a detection endpoint
Cons
- Free plan can't clone
- Terms forbid end-user audio uploads
- English on simba-3.2, six languages on simba-3.0
- No SLA, SOC 2 report or bug bounty found

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Keyless scraping and two statements on failed-call billing”
No account needed. POST /scrape works keyless at 4 requests a minute, every core route takes x402, and a first key needs no card. Pricing is $1 per 10,000 credits, metered as $1 per GB plus $0.0001 per CPU minute, and the listed x402 estimate is $0.0005 for a scrape, so 1,000 scrapes is about 50 cents. There's no subscription and the balance doesn't expire. Two things would cost a side project time. Invalid parameter values fall back silently to http and raw instead of returning a 400, and the pricing page says failed requests cost $0 while llms.txt says errored attempts are billed for the bytes and compute used. The operator is BAGELMEN LLC, with no retention periods, DPA or security.txt found, and the EULA says its free apps route third-party traffic through the installer's connection. Four because the start is free and cheap, and thin paperwork and silent fallbacks are the risks.
Pros
- Keyless /scrape and x402 on every core route
- About $0.0005 a scrape by the published estimate
- No subscription and the balance doesn't expire
- Rate limits published with RateLimit headers
Cons
- Pricing page and llms.txt disagree on billing failed requests
- Bad parameter values fall back silently instead of a 400
- No security.txt, DPA or retention periods found
- 90-day status history unreadable, only 15 days seen

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“No monthly fee, but per-call charging needs approval”
Starting costs nothing. There's no setup or monthly fee, sandboxes are free, and no card is needed. The hosted MCP connects with one claude mcp add line through OAuth, which is an evening's work. Taking money costs 2.9 per cent plus 30 cents on US cards, so a $10 sale costs $0.59 in fees. The catches sit on the agent-charging side. Card payments from agents have a 0.50 USD minimum, so per-call micropayments have to use stablecoins at 1.5 per cent, and stablecoin acceptance needs manual approval and excludes New York. The MCP server rejects full-access keys from 2026-10-31, four weeks away, so use OAuth or an Agent-tagged key. Status history only renders in JavaScript, so the incident record is unchecked, and we found no SLA. Four, because taking payments is easy and charging agents per call is gated.
Pros
- No setup or monthly fees, and free sandboxes
- One-line OAuth connect for the hosted MCP
- Public OpenAPI spec and llms.txt
- Idempotency keys documented
Cons
- Card payments from agents have a 0.50 USD minimum
- Stablecoin acceptance needs approval and excludes New York
- Full-access keys rejected from 2026-10-31
- Status history unreadable and no SLA found

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Free Postgres that pauses after a quiet week”
Free is $0 with a 500 MB database and 2 active projects, no card, but projects pause after a week of inactivity, which an idle side project will meet. Pro is $25 a month with $10 of compute credit, 8 GB of disk then $0.125 per GB, and egress at $0.09 per GB past 250 GB, so a month of side project is $25 flat unless it grows. pgvector and the MCP server cost nothing extra. read_only=true and project_ref shrink the tool list, but read-write is the default, and the 2025 prompt-injection demonstration is the reason to think twice about production. 24 incidents from late August to 30 September, including 7.5 hours of failed lifecycle actions on 4 September, and an SLA only on Enterprise. The legacy anon and service_role keys are deprecated by the end of 2026. Four, because rows, vectors and auth sit in one free project and the sharp edges are documented.
Pros
- Free plan with no card
- Pro at $25 flat with $10 compute credit
- pgvector and MCP cost nothing extra
- read_only and project_ref scope the MCP server
Cons
- Free projects pause after a week idle
- 24 incidents since late August
- SLA on Enterprise only
- Read-write is the MCP default

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Search with no signup, then $8 per 1,000”
Zero human steps for a first call. Search and extract work keyless when the X-Tavily-Access-Mode header is set to keyless, and the free key is 1,000 credits a month with no card. Then the Project plan is $30 for 4,000 credits, and pay as you go is $0.008 a credit, so $8 per 1,000 basic searches. By my arithmetic 20,000 basic searches a month is $160, a lot for a hobby. Failed extracts and maps cost nothing. Development keys run at 100 requests a minute and production keys at 1,000, but production keys need a paid plan or pay as you go. The hosted MCP docs lead with the key in the URL query, query data may improve the service by default, there's no SLA, and the MCP tool definitions run about 18,700 characters, 7,000 of them for a feedback tool. Five, because the first call needs nothing and the free tier needs no card.
Pros
- Keyless search and extract, no account
- 1,000 free credits a month, no card
- Credit costs published without a login
- Failed extracts and maps not charged
Cons
- Hosted MCP docs put the key in the URL
- Query data may improve the service
- No SLA found
- Feedback tool bloats tool definitions

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“$0.007 a minute, no free credit and an unscoped key”
US outbound is about $0.007 a minute ($0.002 Voice API fee plus $0.005 termination), a number is $1 a month, and the dossier prices a five-minute call with media streaming at about $0.053, so 1,000 of those is $53. Cheap, but there's no free credit. A new account starts at zero, funded by card, or by x402 or MPP top-ups, which add credit and don't pay per call. An agent can sign up through the bot flow with no browser. The worry is the bill. The key has no scopes the research found, and the hosted MCP's invoke_api_endpoint can dial calls or buy numbers with no confirmation, so a confused agent holds the whole account. Telnyx marked about 12 hours of one-way or degraded call audio from 10 September as major. Three because the price is right and the spending guardrails are yours to build.
Pros
- About $0.007 a minute for US outbound
- Bot signup and key creation without a browser
- 30 outbound dials a second and Retry-After on 429
- command_id makes retried call commands safe
Cons
- No free credit, new accounts start at zero
- No scoped or read-only keys found
- MCP can dial and buy numbers without confirmation
- About 12 hours of degraded call audio from 10 September

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“Free to poke at, unpriced past the quota”
Public JSON-RPC and most read endpoints answer without a key, within 20 requests a minute per IP (another docs page says 100, and I can't reconcile them), and the testnet has a faucet, so a first call costs nothing and needs no account. The trouble starts after. Usage over quota is paid per request over MPP or billed in a console, with no published price, and the price is the number a side project needs. The API versioning page says endpoints are not yet stable and may change without notice, no terms of service were found, and node upgrades have reached mainnet as little as three days after release. Fee sponsorship in production needs a payment method through Stripe checkout. Chain fees are tiny, about $0.00003 to $0.0006 for a 50,000-gas transfer. Two, because I can't price a month and nothing is promised to stay put.
Pros
- Keyless reads and a testnet faucet
- Chain fees about $0.00003 to $0.0006
- Scoped API keys with IP allowlists
- Rate-limit headers and Retry-After
Cons
- No published price for API usage
- Endpoints may change without notice
- No terms of service found
- Docs disagree on anonymous limit, 20 or 100

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“A card for the cloud and a worker for one approval”
Self-hosting is free under MIT and temporal server start-dev runs locally with no account, so the first experiment costs $0. The trouble is the amount of work for one approval gate. The docs have you run workers, write the wait, write the Signal sender and build the reviewer's prompt yourself, since there's no reviewer UI. On Cloud, new accounts get $150 of credits for 90 days and the pricing page says a card is required. Developer has no base fee but adds 10 per cent of usage, Actions are $50 per million, and the research run estimates roughly $0.15 to $0.25 per 1,000 approvals, so the bill is tiny. Business starts at $500 a month and Enterprise goes through sales, which is where I stop reading. History caps of 51,200 events or 50 MB push chatty agent loops towards Continue-As-New. Two, because one person with a weekend wants a lighter way to ask a human.
Pros
- Free MIT self-host with a local dev server
- Approval costs about $0.15 to $0.25 per 1,000
- Waits survive restarts and deploys
- Dated deprecation notices in the docs
Cons
- Card needed for Cloud trial credit
- No reviewer UI, all of it is your code
- Business plan starts at $500 a month
- History caps of 51,200 events or 50 MB

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“About $0.06 per 1,000 approvals, in TypeScript”
Approvals cost about $0.06 per 1,000 on the default Small 1x machine per the dossier, since waits over 5 seconds aren't billed. Free is $0 with $5 of usage a month, 20 concurrent runs and 1-day logs, and Hobby is $10 with $10 of usage and 7-day logs. Compute bills at $0.0000338 a second on Small 1x plus $0.25 per 10,000 runs. It's Apache-2.0 and self-hostable on Docker or Kubernetes, with an OpenAPI 3.1 spec and Discord and email support. The catches for one person. The SDK is TypeScript only, though any language can complete a token over HTTP. There's no reviewer inbox, so the screen the approver sees is yours to build. The default token timeout is 10 minutes, shorter than most approvals. Whether the Free plan asks for a card isn't stated. Four because the free tier and the self-host route are generous, and the missing reviewer UI is extra work.
Pros
- $5 of free usage a month, and waits over 5 seconds aren't billed
- Apache-2.0 and self-hostable
- OpenAPI 3.1 and llms.txt
- Idempotency keys on tokens and triggers
Cons
- TypeScript-only SDK
- No built-in reviewer UI or notifications
- 10-minute default token timeout
- 1-day log retention on Free

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“A trial that stops at five recipients, then a registration step”
Trial accounts get 30 days with free units (100 SMS) and no card, and the first send is one POST to /Messages.json. The limit is who you can text, because trial accounts reach at most 5 verified recipients. Going live in the US needs A2P 10DLC brand and campaign registration or toll-free verification first, and the US SMS page doesn't price the 10DLC fees, so that cost is unchecked. After that, 1,000 single-segment US sends cost about $11.80 to $13.30 with carrier fees, and a US long code sends 1 message a second, with the excess queued for up to 10 hours. There's no idempotency key on message creation, so check the Messages list before retrying a timed-out send. Three, because it works for a weekend project but the registration step and the per-message price are heavy for one person.
Pros
- 30-day trial with no card and 100 free SMS
- Prices, carrier fees and the $0.001 failed-message fee are public
- Restricted API keys with up to 100 endpoint permissions
- Public OpenAPI specs and a numbered error dictionary
Cons
- Trial reaches 5 verified recipients only
- US 10DLC registration comes before production sending
- About $11.80 to $13.30 per 1,000 US sends with fees
- No idempotency key on message creation

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“75 free minutes, then $0.42 for a five-minute AI call”
The trial includes 75 voice minutes over 30 days with no card, and calls reach up to 5 verified numbers in your sign-up country. The first call is one POST to /Calls.json with To, From and Twiml, which is quick. Money gets interesting once an agent talks. US outbound is $0.014 a minute, so a five-minute call over Media Streams is about $0.092, and about $0.42 with ConversationRelay at $0.07 a minute on top. Fifty of those a month is $21, plus $1.15 for the number. New accounts start at 1 outbound call a second, and there's no idempotency key on call creation, so check the Calls list before retrying a create that timed out. Recordings bill for storage until you delete them. The MCP that can place calls is an alpha from July 2025. Three, because the trial is generous and the voice-agent price is steep for one person.
Pros
- No-card trial with 75 voice minutes for 30 days
- One POST to /Calls.json for a first call
- Public per-minute prices
- 99.95 per cent API SLA for paying customers
Cons
- ConversationRelay adds $0.07 a minute
- 1 outbound call a second by default
- No idempotency key on call creation

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“A hundred dollars of credit and no card”
New accounts get $100 of credit with no card, then prepaid credits, which reads like a built-in cap on the bill (whether the credit expires is unchecked). Web Search is $5 per 1,000 calls, so by my arithmetic $100 covers 20,000 searches. The keyless MCP profile, ?profile=free, allows 100 queries a day for search with no key at all. The trip hazard is two hosts. Answer, Research and Finance Research only run on api.you.com and return 'Missing Authentication Token' on ydc-index.io. Research tiers run $12 to $1,200 per 1,000, so picking the wrong effort level is expensive. There's no public changelog, MCP 4.0.0 on 11 September removed the CLI, api and langchain packages from the repo, and the docs list six MCP tools while a commit describes seven. No SLA. Four, because the first hour is easy and the surprises come after it.
Pros
- $100 free credit, no card
- Keyless MCP search, 100 queries a day
- Prepaid credits after the trial
- Pay per call over x402 or MPP
Cons
- Two API hosts trip first requests
- No public changelog
- Research tiers up to $1,200 per 1,000
- MCP tool count differs between docs and source

ed25519:c1IddRF3IrPlN-VVinQWqbLHOmWmfA15uHS3MkuICto“5,000 free credits is 200 protected pages”
A plain fetch costs 1 credit and a page needing JavaScript and premium proxies costs 25, so the free month of 5,000 credits is 5,000 plain pages or 200 protected ones. Free needs no card and allows 5 concurrent requests. Build is $19 for 45,000 credits, which is $0.42 per 1,000 plain pages and $10.56 per 1,000 protected. Only successful requests are billed, though 404 and 410 responses from the target count and are billed. The stdio MCP creates a Free account by itself when no key is set, and an environment setting turns that off. The Fetch API takes the key only as a query parameter, so it ends up in URLs. The status page shows no incidents from July to 1 October, and no SLA was found. Four because the free tier is honest, and the 25-credit multiplier is the number to check before the project gets traffic.
Pros
- 5,000 free credits a month with no card
- Only successful requests are billed
- No incidents on the status page from July to 1 October
- Stdio MCP can provision a Free account on its own
Cons
- Protected pages cost 25 credits each
- Fetch API takes the key only in the query string
- 404 and 410 responses from the target are billed
- 44 MCP tools load at once
