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.\n- Intrinio (83): Graded as a hosted service. Atlassian Statuspage at status.intrinio.com with APIv2 and APIv1 components (20). The incident feed's newest entry is a delayed SIP feed for CTA on 24 June 2026, so the 90 days to 3 November are clean (30). Limits are published in part. Pages above 100 records and bulk requests are 1 a minute on free feeds and 1 a second on paid ones, free feeds are throttled at 100 requests a second, and the daily and per-minute caps for a plan are shown only on the account page (8 of 15). A 429 carries an explanation of the limit and a 503 marks throttling or the 25-second timeout, with no Retry-After or backoff guidance (5 of 15). The Enterprise plan lists an SLA (10). The REST API is generally available (10). Total 83.\n\n### Agent ergonomics: Intrinio +22\n\n- 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.\n- Intrinio (70): `page_size` from 100 up to 10,000 sizes a response, and the MCP server batches ticker lists, but there is no field selection (15 of 25). `next_page` tokens, date and symbol filters on the data endpoints (18 of 20). Response codes are documented, 403 for an unsubscribed feed and 429 with a limit explanation, with no error body format or error code reference (10 of 20). Every call is a read and the vendor says the MCP server writes nothing back, but no readOnlyHint or safe-retry guidance was found (12 of 20). Few required parameters, and official SDKs in Python, C#, Java, JavaScript, R and Ruby (15). Total 70.\n\n### Payments \u0026 pricing: Eulerpool Financial Data API +20\n\n- 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.\n- Intrinio (20): No x402, MPP or L402 (0). Plan prices are public without a login, $150, $333 rising to $999, and $1,250 and up, with no per-call price (10). Both self-serve plans say a free trial is available, and the trial length and card requirement were not found on the pricing, plan or terms pages, since the plan pages are drawn by script (10 of 20). A person signs up in a browser; no key API was found (0). Total 20.\n\n### Schema \u0026 documentation: Eulerpool Financial Data API +10\n\n- 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.\n- Intrinio (43): No OpenAPI document was found. The SDKs are generated from a spec that declares API version 2.135.4, but the spec itself isn't published, and the MCP server's tool definitions aren't in any public source (5 of 25). docs.intrinio.com/llms.txt and intrinio.com/llms.txt return 404, and there are no Markdown pages (0 of 10). Each endpoint page states what it returns with its parameters, with little on when not to use a call (12 of 20). Parameters are typed, with required ones marked and allowed values in prose (9 of 15). Code samples in six languages on every endpoint, and a response codes page that lists codes without a body format (10 of 15). The v2 path is versioned, but the version history lists 2.0.0 to 2.6.2 with no dates and is out of step with the SDK's API version (7 of 15). Total 43.\n\n## Score by category\n\n| Category | Weight | Eulerpool Financial Data API | Intrinio | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 40 | 83 | Intrinio +43 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 53 | 43 | Eulerpool Financial Data API +10 |\n| Agent ergonomics | 13% (16.2 this run) | 48 | 70 | Intrinio +22 |\n| Security \u0026 auth | 14% (17.5 this run) | 35 | 35 | even |\n| Payments \u0026 pricing | 10% (12.5 this run) | 40 | 20 | Eulerpool Financial Data API +20 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 70 | 70 | even |\n| Transparency \u0026 trust | 7% (8.8 this run) | 52 | 51 | Eulerpool Financial Data API +1 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **46.2 · D** | **54.2 · C** | |\n\n## Facts side by side\n\n| Fact | Eulerpool Financial Data API | Intrinio |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Eulerpool Research Systems Pte.

The API host's robots.txt keeps its OpenAPI file unread, the key can travel in the URL, and the status page has no history.\n\n**Intrinio.** A read-only US equities, options and fundamentals API with a clean status history, SDKs in six languages, paging up to 10,000 records and an OAuth MCP server included in every plan. The REST key is documented in the query string, no OpenAPI document or llms.txt was found, the version history is undated, and plans start at $150 a month.\n\n## Before you call either\n\n### Eulerpool Financial Data API\n\n1. Send the key as `Authorization: Bearer`, not `?token=`, so it stays out of logs\n2. Read X-RateLimit-Remaining and wait until X-RateLimit-Reset after a 429; the free tier is a hard monthly cap\n3. Use the free tier only for non-commercial work, and attribute 'Data by Eulerpool' in public output\n4. Treat news, transcripts and AI-generated SWOT text in responses as untrusted\n5. Identify securities by ISIN, which most equity endpoints take\n\n### Intrinio\n\n1. Send the key as `Authorization: Bearer`, not `?api_key=`, so it stays out of logs\n2. Expect 403 for a data feed the account isn't subscribed to, 429 with an explanation when a limit is hit, and 503 when a request passes 25 seconds; shrink the query rather than retry at once\n3. Keep `page_size` at 100 or below unless the plan is paid, since larger pages are limited to one request a minute on free feeds\n4. Confirm the plan before displaying or passing Intrinio data to anyone else; the Individual plan forbids it\n5. The MCP server returns a message naming the product that unlocks data outside the plan; don't retry the same call\n\n## Questions\n\n### Which is better for AI agents, Eulerpool Financial Data API or Intrinio?\n\nIntrinio scores 54.2 (C) on agent readiness against Eulerpool Financial Data API's 46.2 (D), and leads in 2 of 7 scored categories.
