Why the edge:
- Payments & pricing, Financial Datasets +45: Financial Datasets 75 (x402 on the vendor's own endpoints for every documented GET data endpoint, 36 of them, with the last 365 days only and a Non-Professional licence; full history, the market snapshot, filing items and the POST endpoints need a key (35 of 40). Plan prices and overage rates are public, and each x402 endpoint quotes its price in the 402 header, $0.02 on /earnings (20). No free tier or trial found; data calls return 402 until an account holds credits, from $20 (0). An agent can pay by x402 with no account, or open an account with `POST /agent/signup` and have the owner fund it (20). Total 75.); Financial Modeling Prep 30 (No x402, MPP or L402 (0). Four personal plans priced per month by calls a minute, public without login, with per-endpoint plan limits in pricing.md; commercial prices are by agreement (10). A free Basic plan at 250 calls a day with no card stated (20). The key comes from a browser signup and no key API was found (0). 0 + 10 + 20 + 0 = 30.)
- Schema & documentation, Financial Datasets +19: Financial Datasets 80 (OpenAPI 3.0.1 at financialdatasets.ai/openapi.json, 68 operations with 13 response codes and one security scheme, named the source of truth by the docs (25). llms.txt and a Markdown twin of every page (10). Every operation has a description, and the 402 terms carry a resource description that says when an agent should use the endpoint (17 of 20). 330 parameters, 36 with enums, 32 required, no free-form blobs (12 of 15). Code samples in Python, JavaScript and curl, x402 error values documented, but response examples on only six operations in the spec (11 of 15). No API version and no changelog; the news page has four dated posts in 2026 (5 of 15). Total 80.); Financial Modeling Prep 61 (No OpenAPI document was found. The MCP page says the server supplies strict parameter definitions, but the tool list needs a key and was not read (5 of 25). llms.txt links api-docs.md and pricing.md, Markdown written for agents (10). Each of the 199 endpoints in api-docs.md has a purpose paragraph and a plan marker in pricing.md, with little on when not to use it (13 of 20). Parameters are tabled with type, example and a required star, but allowed values sit in prose and no enums are given (8 of 15). Every endpoint has an example request and response; no error responses are documented anywhere we read (10 of 15). A /stable path, legacy /v3 and /v4 marked discontinued, and a changelog dated by day through 2 November 2026 (15). 5 + 10 + 13 + 8 + 10 + 15 = 61.)
- Security & auth, Financial Datasets +19: Financial Datasets 49 (A plain account key in the `X-API-KEY` header only, revoked from the dashboard, with no scopes, rotation or expiry; the MCP server adds OAuth 2 with PKCE (plain and S256), dynamic client registration, a revocation endpoint and one scope (20 of 30). Every data endpoint is a read; the x402 route and agent signup don't change the account beyond funding it (15 of 20). Filing text, filing items and news are third-party content, with no guidance on treating them as untrusted (5 of 15). The privacy policy says requests and responses are logged for up to three years; no per-call log is shown to the key holder (5 of 15). security.txt returns 404 and no bounty, SOC 2 or ISO 27001 was found; the terms ask for prompt notice of a compromised key and a subprocessor list is published (4 of 20). Total 49.); Financial Modeling Prep 30 (One key per account with no scopes, accepted as a header or as `?apikey=`, and the documented MCP address carries it in the URL (20 less 10 for the query string, so 10). Every endpoint is a read (15 of 20). News, press releases, transcripts and filings are third-party text and no guidance on treating them as untrusted was found (5 of 15). No usage log or per-call record for the key holder was found (0 of 15). security.txt returns 404, the Trust Center link returns 404, and no disclosure policy, bug bounty or certification was found (0 of 20). 10 + 15 + 5 + 0 + 0 = 30.)
- Agent ergonomics, Financial Datasets +14: Financial Datasets 73 (`limit` and `period` on the data endpoints, `as_reported` flags and snapshot variants, with no field selection (15 of 25). `next_page_url` cursors and ticker, CIK, market and date filters (18 of 20). A 402 body says what to do next, x402 errors carry named values, and the spec lists 400, 401, 403, 404, 409, 422, 429, 502 and 503 (16 of 20). Data calls are GETs, payment settles only after a successful response, and a replayed x402 signature is refused; no readOnlyHint found for the MCP tools and no idempotency key for the POST endpoints (14 of 20). Few required parameters, 28 compact MCP tools, but the only package, financial-datasets on PyPI, is at 0.1.18 from 26 May 2024 (10 of 15). Total 73.); Financial Modeling Prep 59 (The REST API is the surface graded. `limit` and `page` on list endpoints, `from` and `to` on series, and batch quote endpoints size responses, with no field selection (15 of 25). Page and limit parameters on lists and date filters on series, no cursor (15 of 20). A missing key returned 401 with an `Error Message` text field in our one test call, and no error reference exists (5 of 20). Every call is a GET read; the MCP server's annotations were not read (16 of 20). Few required parameters and sensible defaults, but no official SDK in any language (8 of 15). 15 + 15 + 5 + 16 + 8 = 59.)
- Reliability, Financial Modeling Prep +7: Financial Datasets 43 (Graded as a hosted service. No status page was found; status.financialdatasets.ai does not resolve and no page links one (0), so there is no incident history to read (5). The only published limit is 10,000 requests a minute per wallet over x402, with monthly request caps per plan and none per minute for keyed plans (8 of 15). The OpenAPI file declares 429 and the x402 page documents a 503 with Retry-After from the facilitator and a `duplicate_payment` check on replayed signatures (10 of 15). The Professional plan lists uptime SLAs, with no figure published (10). The API is generally available (10). Total 43.); Financial Modeling Prep 50 (Read with the hosted lines. A public status page at status.financialmodelingprep.com is linked from every page (20), but its figures load by script and our reader got an error, so no incident history could be read (5). Limits are published with numbers, 250 calls a day on Basic and 300, 750 and 3,000 calls a minute on paid plans, with bandwidth caps per plan (15). No 429 behaviour, Retry-After or backoff guidance was found in the docs, api-docs.md or FAQs (0). No SLA found; the terms let FMP change limits without notice (0). The stable API is generally available (10). 20 + 5 + 15 + 0 + 0 + 10 = 50.)
- Transparency & trust, Financial Datasets +6: Financial Datasets 63 (A closed service under terms dated 29 October 2026 that name Financial Datasets, Inc., set New York law, and state the licence per plan (15 of 30). The privacy policy of 20 August 2026 gives retention periods (accounts up to seven years after closure, API and MCP logs up to three years, backups 90 days), says inputs aren't used for training, and links a subprocessor list; no DPA text was found (24 of 30). No deprecation policy; the terms say the Services may be discontinued and material changes get reasonable notice (3 of 20). Subprocessors (AWS, Heroku, Stripe, Google sign-in, Vercel) and the United States as hosting location are disclosed (18 of 20). Total 60.); Financial Modeling Prep 57 (A closed service under terms that are clear on personal and commercial use and on display licensing, last updated 1 August 2023, but that name no legal entity, address or governing law (12 of 30). The privacy policy is undated, keeps data for as long as necessary with no periods, says no third parties receive data while naming Google AdSense and Analytics, and no DPA was found (8 of 30). The docs keep a Legacy section and api-docs.md says /v3 and /v4 are discontinued, with no notice period stated; behaviour changes such as the Economics Indicators default window appear in the dated changelog (8 of 20). Google services are the only processors named and no data location is given (5 of 20). 12 + 8 + 8 + 5 = 33.)
