letme vs SandBase

letme 81

The editorial half, for the service as a whole. Closed source with no public repository (about page). The terms of 14 October 2026 cover letme.dev under the law of England and Wales, and the data letme hands out is CC BY 4.0, with the credit rule in every answer's directory.credit and in the terms. Read as a closed service with a plainly licensed data output (20 of 30). The privacy policy (17 October 2026) and the trust page (reviewed 15 October 2026) agree on 90-day request records for letme.dev, what each record holds, Global Privacy Control and Do Not Track stopping the record, no model training and hosting on the company's own servers in the United Kingdom. Two statements didn't agree with the privacy policy when this check was made. The about page said nothing on the reading side was tracked, and the trust page said there were no analytics (both corrected on 23 October 2026, after the check), while the privacy policy describes a per-IP record of each request kept 90 days (on letme.dev including what was asked and which listing was picked) and pages reporting searches, links followed, tabs, copies and time in view. No published DPA, available on request (24 of 30). The terms promise 90 days' notice before retiring anything in the API, and the service level of 20 October 2026 promises 90 days' notice before a breaking change to letme's API or MCP tools. No letme deprecation has been issued to show the policy in use, and while the service level says deprecations have always had 90 days' notice, the changelog of 19 October 2026 records an older review format refused on Anchor Terminal's API that day, a day after it was said to stay valid (15 of 20). Sub-processors are listed with what each sees (public blockchain nodes and Anthropic), and data is kept on the company's own servers in the United Kingdom (20).

SandBase 48

The editorial half. The catalogue service, routing, billing, API, MCP server, Agents runtime and sandboxes are closed; the CLI, bridge, skill, catalogue, examples and SDKs are Apache-2.0. The terms (14 October 2026) name AXIOMCLOUD PTE. LTD. under Singapore law and cover agents, scraping APIs, provider licences and billing, with no registration number or address on any page read. Paid, Nevermined and Monid earned 17 for closed platforms with open SDKs (17 of 30). The privacy policy (30 October 2026) names the company, lists the customer content it handles and says the information an operation needs goes to the selected provider. It states no retention periods ('We do not claim a universal retention duration'), says only that it 'does not grant SandBase an unrestricted right' to use private content, and asserts no transfer mechanism. It agrees with the terms but leaves retention and training open. OpenRouter earned 15 where the policies settled storage, and Monid 5 where they were silent on run data (12 of 30). No deprecation policy or dated notices. The terms promise notice of material changes and say that beta parts of the service 'may change, have quotas or be discontinued', and the pricing page promises notice before sandbox pricing changes (3 of 20). The policy names Cloudflare, Google and GitHub sign-in, Stripe, Airwallex, Google Analytics 4 and PostHog (United States), but not the hosting provider, other data locations or the model and data providers. Monid earned 6 and Nevermined 14 (9 of 20). 17+12+3+9 = 41. The provenance half is computed from the provenance block.

letme 85

Read with the hosted lines, for the HTTP GET and POST interface and the MCP endpoint at /mcp, which run as one service on one host, so the points are the same for both. Anchor Terminal's own status page at anchorterminal.com/status/ has a letme section with uptime by day and an outage list, from probes every five minutes (20). It records no outages from 2 to 23 October 2026. The record is three weeks long, the probes run on the same machine as letme.dev, so an outage of the whole machine leaves no record, and the page marks 15 of its 22 days as partly watched, every day from 9 to 22 October among them (247 to 256 of 288 probes). Read as a clean record that is weak evidence, as the calibration read one (20 of 30). Limits published as 20 requests a second per IP address with bursts of 40, in llms.txt, the OpenAPI file and the Agent Skill (15). 429 with Retry-After 1 and rate_limited, and 503 with Retry-After while letme restarts with the advice to retry once, all documented. Every pick is a read and nothing is billed. We didn't trigger a 429, to keep our calls to letme.dev low (15). A service level since 20 October 2026 sets 99.9% availability a calendar month with a post-mortem for any outage over 15 minutes, and no money back because letme is free. Read as a published target without remedies (5 of 10). Picking is live with no beta or preview label, and calling through letme isn't open and earns nothing (10). Checked between 14:33 and 14:40 UTC on 23 October 2026.

SandBase 63

Hosted lines, graded on the HTTP API and the remote MCP server at api.sandbase.ai/v1/mcp, the surfaces an agent calls. status.sandbase.ai is a live Better Stack page with a 90-day view of the website, the API, the docs and the blog, and no component for the MCP path or sandbox.sandbase.ai. Monid earned 15 for a live Better Stack page that didn't monitor its MCP host (15 of 20). Read on 8 November 2026, it showed all services operational, the API at 99.957 per cent over 30 days and 99.983 per cent over 90, and 'No incidents reported' for September, October and November 2026. That is under 20 minutes of API downtime in the last 30 days and no outage of an hour, so minor incidents at most (20). The rate-limits page says requests a minute are assigned per organisation over a one-minute sliding window, shared by its keys, with a video concurrency limit, and publishes no numbers. Paid and Monid earned 7 for limits described without numbers (7 of 15). A 429 carries {"error":"organization rate limit exceeded"}, Retry-After is 'not guaranteed' and honoured when present, and the docs give exponential backoff with jitter and say not to retry a state-changing request without documented idempotency. Idempotency-Key is taken on Agents writes, session events and cancel, not on POST /v1/run, which spends money. Monid earned 11 on the same pattern (11 of 15). No SLA, and the terms promise no uptime, response time or availability (0). No beta or preview label on the API or the MCP server (10). 15+20+7+11+0+10 = 63.

letme 60

For both interfaces. No x402, MPP or L402 on any letme endpoint today. x402 top-ups are specified on /letme/ for when calling opens and earn nothing (0). Free, stated in llms.txt ('Nothing here is billed'), the terms and /letme/ (20). No card and no account (20). Keyless over HTTP and MCP, so an agent gets its first answer with no signup (20).

SandBase 40

No x402, MPP or L402 on the home page, pricing, billing, llms.txt or the OpenAPI paths; the balance is funded through Stripe or Airwallex checkout (0). Prices per million tokens, per image, per seconds of video or per call on public pages without a login, such as anthropic/claude-sonnet-5.5 at $1.70 in and $8.50 out per million tokens, and inspect returns each price before a run (20). Every organisation gets 100 free calls a day on eligible data APIs, which a zero-balance organisation can still use per the skill, and Start is $0. No card requirement was found on the pricing page or the billing guide, which asks for a saved card only for auto top-up. Nevermined earned 20 for a free plan with no card requirement found (20). A person approves a browser sign-in, through the CLI's flow or the console, before any key exists, and no keyless or programmatic route was found (0). 0+20+20+0 = 40.

letme 88

For both interfaces. OpenAPI 3.1 at letme.dev/openapi.json with 9 paths and 10 operations, and typed JSON Schema inputs with additionalProperties: false on both MCP tools, pick and about, read from tools/list at 14:38 UTC on 23 October 2026 (25). llms.txt, an Agent Skill, and Markdown answers with a .md suffix or Accept: text/markdown (10). The tool descriptions and the OpenAPI operations say what each returns and that nothing is called, and the MCP server instructions and the Skill say when to use letme. The tool definitions themselves don't say when not to use them (16 of 20). minGrade, keyless and x402 are enums, n is bounded 0 to 10 and about requires slug, but where, kind, auth, pricing and not are comma-separated strings with their values listed only in descriptions, the pick tool marks no field required, and POST /report has no request schema in the OpenAPI file (11 of 15). An example on every parameter and on the POST body, and 400, 404, 429 and 503 documented with schemas, which the live 404 answer matched. No response examples, the error code is a free string, and the 405 calling_not_open and 404 own_listing answers aren't in the OpenAPI file (13 of 15). The build version 2026.10.22-0655 is in the X-Letme-Build header, the OpenAPI info.version and MCP serverInfo, letme changes go in the dated changelog at anchorterminal.com/changelog/, and the service level of 20 October 2026 promises 90 days' notice before a breaking change. There's no version in the path or API version apart from the build stamp, and the 22 October build has no changelog entry of its own (13 of 15).

SandBase 76

A public OpenAPI 3.1 file at www.sandbase.ai/openapi.json (SandBase API 1.0.0, server https://api.sandbase.ai), linked from llms.txt, covers the OpenAI, Anthropic and Gemini compatible routes, /v1/run, the data API passthrough, uploads, assets, models, account, webhooks, Agents and Sessions. Our reader stopped at about 110,000 characters, before components, so the security schemes and error schemas weren't read, and the hosted MCP tool list wasn't read; the bridge's built-in definitions give JSON Schema for all seven tools. Missing routes and unread MCP tools took 22 for Monid and Nevermined (22 of 25). llms.txt, llms-full.txt, Markdown docs and a 'For AI agents' section (10). The skill says when to use SandBase and when not to (the user's own tools and built-in search first), and the bridge's descriptions say 'Always inspect before running', but each tool description is one line and the live server's text is unread. Monid took 15 with its MCP text unread (15 of 20). The bridge schemas have required fields, additionalProperties: false and an enum on discover's type, but limit has no bounds and sandbase_run takes arguments as a free object typed only through inspect. Monid's untyped run body took 11 (11 of 15). Examples in curl and SDKs throughout, and an errors guide with a status table and recommended actions, but no list of named codes, and core platform errors can be a flat {"error": "..."} string. Monid earned 14 with a 19-value code field (11 of 15). Path versioning under /v1 and dated CLI tags, but no changelog for the API, the MCP server or the platform. Paid earned 7 for versioning with no API changelog (7 of 15). 22+10+15+11+11+7 = 76.

letme 57

For both interfaces. No credential of any kind, so there's nothing to leak and nothing to scope, rotate or revoke, read as for other keyless services (20 of 30). Every MCP tool and every GET is a read, and nothing can spend money. The one write, POST /report, adds an unauthenticated outcome count to the public stats, limited only by the per-address rate limit, read as for a keyless service with one unauthenticated write (14 of 20). Answers carry Anchor Terminal's own directory records (endpoint, auth notes, connect snippets, agent notes), not content passed through from third parties, and every answer and the MCP instructions carry the CC BY credit rule addressed to the agent. No prompt-injection guidance found (10). No account, so no per-call view for an operator. Every answer we read, the 404 included, carried an RFC 9421 Ed25519 signature with the keys at /.well-known/http-message-signatures-directory, so a caller can keep a checkable record of its own calls, credited a little (3 of 15). security.txt on letme.dev and anchorterminal.com with Contact, Policy and Expires 2027-10-01 lines, acknowledgement within two working days and a published fix note per the about page, and good-faith reporting protected in the terms. No bug bounty, no SOC 2 or ISO 27001 (the trust page says so), and no advisories found (10 of 20).

SandBase 45

Standard keys (sk- and 64 hex characters) act for one organisation with no user-selectable scopes, can carry an expiry and a spending limit, are shown once and are revoked permanently in the console. CLI Login keys from the browser approval (device secret plus PKCE S256) are scoped to mcp:invoke and answer 403 insufficient_scope outside it. No OAuth for the MCP server and no API for managing keys. Above plain revocable keys, below OpenRouter's 25 with OAuth PKCE and a management API (22). The OpenAPI file's generateContent operation 'also accepts x-goog-api-key and the key query parameter for Google SDK compatibility', noting headers are safer, and all four Gemini operations list a GoogleQueryApiKey scheme, read on 8 November 2026. A secret in a URL query string is a documented option, so 10 off (12 of 30). Per-key spending limits and expiry, the organisation's funding boundary and a monthly limit on auto top-up bound spend, and an agent can't lift a key's limit by topping up. No read-only key, per-period budget, per-run cap, allowlist of tools or providers or approval step before a paid run. Monid earned 16 with per-period budgets, a per-run cap and read-only scopes, which SandBase lacks (12 of 20). Runs return scraped pages and social posts from third parties, and neither the skill nor the docs read say to treat them as untrusted. Monid took 3 with none (3 of 15). Request history lists each request's status and cost, sandbase_runs and account history return runs with cost, GET /v1/tasks/{task_id}/cost gives a task's cost, and billing records export as CSV. No key-level audit (created by, last used) was found. Monid earned 13 with key usage records (12 of 15). security.txt answered a client error. SECURITY.md in sandbaseai/sandbase names the SDKs, examples, catalogue and API as in scope for GitHub private vulnerability reporting with acknowledgement within 3 business days, and the CLI repository has its own. No bug bounty or certification found. Paid earned 6 for a reporting address without security.txt (6 of 20). 12+12+3+12+6 = 45.

letme 58

Read as a closed service, for both interfaces. Build 2026.10.22-0655 was live on 23 October in the answer headers, the OpenAPI file and MCP serverInfo, and the latest dated letme entries in the changelog are from 20 October 2026 (30). Dated letme entries on 1, 2, 5, 14, 15 and 20 October 2026 (20). A public changelog, contact by email and form, and a public issue tracker since 20 October 2026 that held no issues on 23 October, so there's no reply record to judge (8 of 15). Not in the official MCP registry, where searches for letme, anchorterminal and com.anchorterminal on 23 October found nothing of letme's, and no official SDK (0). No package, dependencies or CI can be seen from outside, since the code is closed. The changelog describes a test that keeps the documented limit and the nginx config the same (2 October) and deploys checked before they take requests (5 October), neither of which can be inspected, so nothing to score (0 of 10).

SandBase 68

Read for a hosted service with an open CLI and SDKs. sandbaseai/cli tagged v0.3.9 on 7 November 2026, npm @sandbaseai/cli 0.3.8 was published on 25 October, and the catalogue repository refreshed on 8 November (30). Tags v0.1.14 to v0.1.17 on 15 and 19 August, v0.3.0 to v0.3.6 on 11 and 12 October, v0.3.8 on 24 October and v0.3.9 on 7 November (20). The platform is closed and GitHub's API refused the graders, so issue queues are unread and the 0 to 15 scale for closed services applies. No public changelog for the API or MCP server, support by GitHub Discussions, issue forms and Discord (untested), and every merged pull request came from a sandbaseai branch, with commits from two people under three account names. Paid earned 5 with a support channel and no changelog, and Monid 6 with merged outside pull requests (5 of 15). The official MCP registry couldn't be read (the fetch needed an approval that didn't come), so presence there scores absent although server.json declares io.github.sandbaseai/cli. Official SDKs in Python, TypeScript and Go exist only in the GitHub repository at 0.1.0, a week old, and the TypeScript README says to copy the file until the npm package is published (5 of 15). CI runs lint, tests, a build and a package audit that rejects lifecycle scripts, with a lockfile and three runtime dependencies, and npm publishing is configured with provenance. CI results weren't read (8 of 10). 30+20+5+5+8 = 68.
