Why the edge:
- Transparency & trust, Eulerpool Financial Data API +25: Eulerpool Financial Data API 52 (Closed service under terms dated 6 November 2026 naming Eulerpool Research Systems Pte. Ltd. of Singapore (15 of 30). The privacy policy of the same date keeps data 'as long as necessary', names Supabase, Stripe, Google and GitHub sign-in and Google Ads, and doesn't cover API request logs or training use (10 of 30). No deprecation policy or notices found (0 of 20). Some processors named; hosting location not stated (8 of 20). 15+10+0+8 = 33.); Finnhub 27 (A closed service whose terms exist at a page that robots.txt disallows, so they were not read; the pricing page says every self-serve plan is personal use, and no legal entity or governing law was found (8 of 30). No privacy policy was found, /privacy redirecting to the home page (0 of 30). No deprecation policy or dated notices found (0 of 20). Stripe and Braintree scripts load on the site, but no processor list or data location is disclosed (0 of 20). 8 + 0 + 0 + 0 = 8.)
- Payments & pricing, Eulerpool Financial Data API +10: Eulerpool Financial Data API 40 (No x402, MPP or L402 (0). Plan prices and overage per 1,000 requests are public (20). 100,000 free requests a month with no card, non-commercial (20). A person registers in a browser (0). 0+20+20+0 = 40.); Finnhub 30 (No x402, MPP or L402 (0). Plan prices are public without login, read from the pricing page's script data, sold per dataset by the month with calls a minute rather than per call (10). A free key at 60 calls a minute with no card, which the pricing FAQ says can be used forever (20). The key comes from a browser signup and no key API was found (0). 0 + 10 + 20 + 0 = 30.)
- Maintenance & community, Eulerpool Financial Data API +10: Eulerpool Financial Data API 70 (Closed service. The changelog's newest entry is dated 6 November 2026 (30), with daily entries through October, though many are tutorials rather than API changes (20). Contact by email; no public tracker or community found (5 of 15). Official SDKs in four languages, published 13 September 2026 (12 of 15). Package health not checked (3 of 10). 30+20+5+12+3 = 70.); Finnhub 60 (Read as a closed service. The newest dated change is 2 November 2026, when finnhub-go, finnhub-ruby and finnhub-php gained a price target history endpoint; the MCP page is dated 6 August 2026 (30). Only that one dated change falls in the last 90 days, the previous library commits being 22 June 2026 (5 of 20). Support by email, with no public changelog or community channel found (5 of 15). Six official client libraries, finnhub-python at 2.4.29 of 24 June 2026 (15). The libraries are generated from the API document; no CI run was visible and the Python README names an older version than PyPI (5 of 10). 30 + 5 + 5 + 15 + 5 = 60.)
- Reliability, Finnhub +8: Eulerpool Financial Data API 40 (Hosted lines. The status page lists three components with checks that were still loading, no history and a note that incident reporting is 'coming soon' (5 of 20). No incident history (5). Monthly quotas per plan are published, with no per-second figures (10 of 15). 429 at the free cap with X-RateLimit headers and a reset timestamp, no Retry-After or backoff guidance (10 of 15). No SLA found (0). Generally available (10). 5+5+10+10+0+10 = 40.); Finnhub 48 (Read with the hosted lines. No status page was found on the site, in the docs document or on the MCP page (0), so no incident history could be read (5). Limits are published with numbers, 60 calls a minute on the free key, 150 to 900 a minute by plan, and 30 calls a second on top of every plan (15). The docs say the limit answers 429 and the MCP page says to wait a minute, with no Retry-After or backoff guidance (8 of 15). The home page says 99.99 per cent uptime with an SLA available for enterprise clients (10). The API is generally available (10). 0 + 5 + 15 + 8 + 10 + 10 = 48.)
- Agent ergonomics, Finnhub +8: Eulerpool Financial Data API 48 (The MCP page claims 157+ tools with no toolsets or list, and response sizing on the API wasn't documented in the pages read (8 of 25). Filtering and pagination not documented in the pages read (8 of 20). Error codes not documented in the pages read (5 of 20). The data endpoints are reads (12 of 20). Official SDKs in Python, JavaScript, Node.js and Go (15). 8+8+5+12+15 = 48.); Finnhub 56 (The REST API is the surface graded. `from` and `to` on candles and news, and symbol-scoped calls, size responses; no field selection, and the MCP server lists 70 tools (12 of 25). Date filters but no pagination on most lists (10 of 20). Only the 429 is documented; a missing key answered 401 with a JSON `error` field in our one test call (5 of 20). All but one operation are GET reads; the MCP annotations were not read (14 of 20). Few required parameters and official libraries in six languages (15). 12 + 10 + 5 + 14 + 15 = 56.)
- Schema & documentation, Finnhub +5: Eulerpool Financial Data API 53 (An OpenAPI 3.0 document is linked at api.eulerpool.com/api/1/documentation/yaml, but that host's robots.txt disallows every path, so it was not read; partial credit for a linked contract we couldn't check (10 of 25). llms.txt, a 449-entry endpoint index and a 13,904-line llms-full.txt (10). Endpoint descriptions say what each returns, with the same marketing sentence repeated in every section and little on when not to use one (10 of 20). Parameter typing not visible in the llms files read (7 of 15). Response examples throughout; the errors page was not read (8 of 15). /api/1 paths and a dated changelog that mixes API changes with tutorial posts (8 of 15). 10+10+10+7+8+8 = 53.); Finnhub 58 (A public Swagger 2.0 document covers 116 paths with a description on every operation, declaring the key as a query parameter and a 200 response only; the MCP tools were not read (20 of 25). /llms.txt returns the site's HTML shell and no Markdown docs exist (0 of 10). Each operation states its purpose, a premium marker and, on quote, advice against polling, with little on when not to use it (14 of 20). Required flags and types are set on 248 parameters, but allowed values such as news categories sit in description text and no enum is declared (8 of 15). Every operation has example URLs and sample code in five languages, while the only documented error is the 429 (9 of 15). The path carries v1 and no changelog or dated change notes were found (7 of 15). 20 + 0 + 14 + 8 + 9 + 7 = 58.)
