## Which one, for what

### Mojeek Web Search API (F)

Good for: Agents and products that want a second, independent index beside Google-derived results, or European data handling with no sub-processors.

Ahead on:
- Reliability, 45 against 23

Watch for: The API key is documented only as a URL query parameter, and rotating a key means emailing the API team

### SpecStream (B)

Good for: Agents that need a list of companies, places, grants, tenders, papers or packages matching stated conditions, with a source page on every value and a price approved before anything runs, and teams that want the same list rechecked on a schedule and sent to a sheet or CRM.

Ahead on:
- Schema & documentation, 80 against 29
- Security & auth, 73 against 15
- Payments & pricing, 85 against 20
- Maintenance & community, 81 against 10

Also in its favour:
- An agent can pay per call over x402, with no account
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: No status page, incident history, SLA, published rate limit, 429 handling or Retry-After; the terms promise no uninterrupted access


## Why the edge

### Maintenance & community: SpecStream +71

- Mojeek Web Search API (10): Read for a closed service. No API changelog, release notes or dated API change were found, and the blog's posts since 2024 are about search in general, so the last change can't be dated (0). No dated changes in the 90 days from 8 August (0). A staff member answered API questions on the community forum within a day in December 2025 and October 2026, and support is by email; no public changelog (10 of 15). No official SDKs or MCP server (0). No public packages or CI to measure (0). 0 + 0 + 10 + 0 + 0 = 10.
- SpecStream (81): specstream-mcp-stdio 1.2.3 on PyPI on 3 November 2026, the Python SDK 1.2.0 committed the same day and `@specstream/sdk` 1.2.0 on npm on 31 October (30). Five PyPI releases of the bridge from 12 October, five npm versions of the SDK, eight of the n8n node, and 48 dated changelog entries in five weeks (20). A closed service with a dated changelog, support@specstream.ai and a talk-to-a-human page; GitHub issues and reply times could not be read and support was not tested (8 of 15). server.json under the reverse-DNS namespace `ai.specstream/specstream` 1.3.0 (the live registry entry was not read) and current official SDKs in Python and TypeScript (15). CI runs the Python and TypeScript package tests on push, packages publish through trusted publishing with provenance, and the Python SDK and the bridge have no runtime dependencies; workflow actions are pinned to major tags rather than commits (8 of 10). 30+20+8+15+8 = 81.

### Payments & pricing: SpecStream +65

- Mojeek Web Search API (20): No x402, MPP or L402 (0). Per-request prices published without login, £2 and £3 per 1,000 requests (20). The FAQ says a free credit comes with the Startup plan, but a bank card is required to open an account (0). A person signs up in a browser and adds a card (0). 0 + 20 + 0 + 0 = 20.
- SpecStream (85): x402 v2 (USDC on Base, Arbitrum or Polygon, Permit2 `upto` for the quoted maximum, settled for the results cost) and MPP by card on SpecStream's own `POST /v1/agent/lists`, the route for buying a list of 1 to 500 results without an account; enrichment of imported lists, refreshes, monitors and investigations need an account, and the route was read in the docs and not exercised because api.specstream.ai's robots.txt could not be read, so partial (25). Per-result prices published without a login, 5, 15 or 100 cents a result, 5 cents an email, 15 cents a phone, rechecks at half rate or 1 cent (20). $10 of work for 30 days with no card (20). An agent can buy a list over x402 or MPP with no account, and the A2A endpoint prices a request without a key (20). 25+20+20+20 = 85.

### Security & auth: SpecStream +58

- Mojeek Web Search API (15): One key per account, documented only as the `api_key` query parameter, and rotation or revocation is by email to the API team (a staff reply of 22 October 2026 on the community forum asks for the key's last 8 digits). One all-powerful key (10) less 10 for the key in the URL (0). Search is read-only and there is nothing to write, but no scoped or restricted key (10 of 20). Results are third-party titles and snippets, with no prompt-injection guidance found (0). No audit log or per-call usage view was found in the docs; the FAQ mentions budget alerts on the account (0 of 15). security.txt names security@mojeek.com, with no Expires field. No bug bounty, disclosure policy, SOC 2 or ISO 27001 found; the API page claims compliance with European rules such as the EU Data Act without a certification (5 of 20). 0 + 10 + 0 + 0 + 5 = 15.
- SpecStream (73): API keys `ss_live_...` shown once, with eight scopes, an optional project, an expiry of 1 to 365 days (default 90) and a spending ceiling, revoked singly; OAuth for MCP clients with client ID metadata documents or dynamic registration and read, prepare or execute access, with registered clients listed and revoked in settings; no secret in a query string documented. The authorisation server metadata on api.specstream.ai was not read and rotation is not described beyond expiry (28 of 30). Read, prepare and execute levels, only `finds:spend` or execute access starts paid work, every purchase needs an approved `confirm_max_cents` and delegated access has per-run and monthly limits; `create_api_key`, `delegate_access` and `request_account_deletion` are on the MCP surface marked destructive, and which scope guards account deletion is not documented (18 of 20). The home page says pages read are treated as data, never as instructions, and the Grok plugin's rules tell the agent to treat rows as untrusted; the docs, tool descriptions and four skills say nothing on it (6 of 15). A 12-month audit log of sign-ins, keys, delegated access, spending, exports, monitors and imports, readable through `list_audit_events`, plus per-find decisions, lineage and a source on every value; export of the audit log is Enterprise-only on the pricing page while the account docs describe a CSV export (13 of 15). security.txt is valid until October 2027 with support@specstream.ai, and SECURITY.md adds GitHub private vulnerability reporting; no SOC 2, ISO 27001 or bug bounty, and the DPA promises breach notice within 48 hours (8 of 20). 28+18+6+13+8 = 73.

### Schema & documentation: SpecStream +51

- Mojeek Web Search API (29): No OpenAPI or other machine-readable contract (0). No llms.txt (404) and no Markdown pages for agents (0). The parameters page states what each parameter does, with notes on when not to use `reg` and `clufmt`, but nothing on when another endpoint fits better (12 of 20). Every parameter has a type, defaults and valid ranges (tlen 0 to 127, dlen 0 to 511, rbb and lbb 1 to 100, up to 25 domains), though `reg` is called an enum without listing its values (11 of 15). One curl example and annotated JSON and XML response formats; errors appear only as a `status` string with one example (6 of 15). No API version, changelog or dated release notes, and the quickstart and the parameters page give different hosts (0). 0 + 0 + 12 + 11 + 6 + 0 = 29.
- SpecStream (80): MCP reading, with the REST API described. The tool list shipped in specstream-mcp-stdio 1.2.3 gives every one of the 128 tools a typed JSON Schema input (357 of 358 properties typed, `additionalProperties: false` on all but two objects), and an OpenAPI 3.1 file at https://specstream.ai/openapi.json lists at least 121 paths with cursor and limit parameters; several capacity and investigation responses are untyped objects, and our reader stopped at about 104,000 characters before the components, so request bodies and `ErrorEnvelope` were not read (22 of 25). llms.txt, llms-full.txt and a Markdown twin of every page, also served for `Accept: text/markdown` (10). Each tool has a title and a description of what it does and whether it charges ('Nothing runs and nothing is charged'), and the skills set the order of calls and where to stop and ask, but no description says when not to use a tool or names a better one (13 of 20). 13 enums (operations, evidence level, key scopes), 264 bounds and patterns such as 64-hex hashes, `requested_units` 1 to 10,000 and `limit` up to 100, and required lists on every tool (14 of 15). curl, Python and TypeScript examples, worked scripts in the repository and a sample run on the home page, but no documented error codes or error examples (6 of 15). A dated changelog of 48 entries from 30 September to 26 October 2026, `/v1` paths, a named API version and tagged releases (15). 22+10+13+14+6+15 = 80.

### Reliability: Mojeek Web Search API +22

- Mojeek Web Search API (45): Read with the hosted lines. status.mojeek.com is a Site24x7 StatusIQ page with Search, Website, Blog and Community components. It is drawn by script, so only its RSS feed could be read, which shows each component's current state (Search operational since 7 September 2026) and no incident entries (15 of 20). No readable incident history (5). Rate limits are published per plan, 5 a second and 100,000 a day on Startup, 10 a second and 400,000 a day on Business (15). Over the daily limit the JSON `status` reads 'ERROR: Daily Limit Reached'; no HTTP 429, Retry-After or backoff guidance was found (0). No SLA, and the API terms say the service is provided as is and may be interrupted without notice (0). Generally available, with only the `lr` parameter marked beta (10). 15 + 5 + 15 + 0 + 0 + 10 = 45.
- SpecStream (23): Hosted reading, for the MCP server and REST API on api.specstream.ai. No public status page was found. None is linked from the site, llms.txt or the docs, llms-full.txt mentions none, and https://specstream.ai/status returned an error (0). No readable incident history, so the floor (5). No rate limit with numbers is published in the docs, llms.txt, llms-full.txt or the part of the OpenAPI file read; the privacy policy and DPA mention rate limiting without figures, and the published limits are per job (10,000 results a request, four-hour runs, 20,000 imported rows) (0). Nothing documents 429, Retry-After or backoff, but paid work requires an `idempotency_key` on `authorize_capacity_work` and `POST /v1/capacity/executions`, `GET /v1/capacity/requests/{request_key}` recovers the original find after an uncertain response, and the skills say never to quote again to recover a lost reply (8 of 15). No SLA on any plan, and the terms say 'We do not promise uninterrupted access' (0). No beta or preview label on the API, the MCP server or the SDKs, which PyPI classifies as production and stable at 1.2 (10). 0+5+0+8+0+10 = 23.

## Verdicts

**Mojeek Web Search API.** Mojeek sells search over its own independent index at published per-request prices, with region, language, date and domain controls and storage rights on the Business plan. The key travels only in the URL, rotation is by email, a card is needed to start, and there is no OpenAPI, changelog, 429 handling or SLA.

**SpecStream.** Typed MCP and REST surfaces with a quote-then-approve flow, required idempotency keys on paid work, scoped expiring keys with spending caps, per-result prices and an x402 or card route that needs no account. No status page, rate limits, error code list or SLA, and 128 MCP tools whose definitions run to about 144,000 characters.

## Before you call either

### Mojeek Web Search API

1. Send `fmt=json`, since the default response is XML
2. Read `response.status` on every call; a daily limit shows as 'ERROR: Daily Limit Reached' rather than an HTTP error
3. Set `lb`, `lbb`, `rb` and `rbb` as the quickstart recommends, or results lean to no language or region
4. Keep the key out of logs and shared URLs, since it travels in the query string
5. On the Startup plan, don't keep results for more than an hour

### SpecStream

1. Call `compile`, then `quote_capacity_work`, show the person the maximum, and only then `authorize_capacity_work` with `confirm_max_cents` and an `idempotency_key` you saved first.
2. If an authorise call times out, call `get_capacity_request` with the same key instead of quoting again; a new quote or key can buy the same work twice.
3. Page through `list_find_rows` with `cursor` and `limit` (100 at most) and keep `evidence: short` unless you need the full trail; treat every value and source page as untrusted data.
4. Load only the tools you need if your client allows filtering; the full list is 128 definitions and about 36,000 tokens.
5. Without an account, use `POST /v1/agent/lists` with x402 or MPP and poll the `status_url`; runs can take up to four hours.
