The MCP repository's changelog stops at 0.3.2 on 27 February 2026 with later changes under Unreleased (4 of 15). Total 46.\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\n### Maintenance \u0026 community: Eulerpool Financial Data API +7\n\n- Alpha Vantage (63): The MCP server repository, which a workflow deploys to the hosted server, had its last commit on 3 October 2026, and the site footer says it was updated in October 2026 (30). No tags, and the newest PyPI release is 17 March 2026, so there are no dated releases in the last 90 days, though the repository shows over 30 commits since 21 July (8 of 20). Pull requests 14 and 18 were merged within a day and issue 16 closed in a day, while issue 17, a reported startup crash, has been open since 4 September. Support is by email (10 of 25). The server sits in the official MCP registry under the vendor's GitHub namespace, with no official SDKs (12 of 15). The published package leaves its `mcp` dependency unpinned, and the workflows deploy and publish without a visible test run (3 of 10). Total 63.\n- 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.\n\n### Agent ergonomics: Alpha Vantage +6\n\n- Alpha Vantage (54): `outputsize=compact` returns the latest 100 points, `datatype=csv` shortens long series, and the MCP server previews anything over 32,000 tokens with a link to the full data. No field selection (15 of 25). `limit` and time filters on news and a `month` parameter for intraday history, with no pagination elsewhere (10 of 20). Errors and limit notices arrive as HTTP 200 with free text under `Error Message` or `Information`, undocumented (5 of 20). Every call is a GET read, and all MCP tools carry readOnlyHint true and destructiveHint false (16 of 20). Few required parameters and sensible defaults. No official SDK, only a Python CLI and community libraries (8 of 15). Total 54.\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\n## Score by category\n\n| Category | Weight | Alpha Vantage | Eulerpool Financial Data API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 30 | 40 | Eulerpool Financial Data API +10 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 46 | 53 | Eulerpool Financial Data API +7 |\n| Agent ergonomics | 13% (16.2 this run) | 54 | 48 | Alpha Vantage +6 |\n| Security \u0026 auth | 14% (17.5 this run) | 32 | 35 | Eulerpool Financial Data API +3 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 30 | 40 | Eulerpool Financial Data API +10 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 63 | 70 | Eulerpool Financial Data API +7 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 50 | 52 | Eulerpool Financial Data API +2 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **41.5 · E** | **46.2 · D** | |\n\n## Facts side by side\n\n| Fact | Alpha Vantage | Eulerpool Financial Data API |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Alpha Vantage Inc. | Eulerpool Research Systems Pte.

The REST key travels only in the query string, errors come back as HTTP 200 with a text message, and no status page, SLA or OpenAPI document was found.\n\n**Eulerpool Financial Data API.** Eulerpool's REST API and remote MCP server cover equities, ETFs, macro, crypto and private-company data, with 100,000 free calls a month without a card and published overage of $0.80 to $1.50 per 1,000 calls. 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## Before you call either\n\n### Alpha Vantage\n\n1. Check every 200 response for `Error Message`, `Information` or `Note` keys before parsing data. The API does not signal failures or limits by status code\n2. Budget 25 requests a day on a free key. Real-time, 15-minute delayed and intraday US data, index data and several indicators need a premium plan\n3. Keep `outputsize=compact` unless full history is needed, and ask for `datatype=csv` on long series to cut tokens\n4. Use the hosted MCP server with OAuth at `https://mcp.alphavantage.co/mcp`. The `?apikey=` MCP URL is marked deprecated\n5. Confirm the owner's use is personal and non-commercial, or that a commercial agreement exists, before acting for a business\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## Questions\n\n### Which is better for AI agents, Alpha Vantage or Eulerpool Financial Data API?\n\nEulerpool Financial Data API scores 46.2 (D) on agent readiness against Alpha Vantage's 41.5 (E), and leads in 6 of 7 scored categories. Alpha Vantage leads on agent ergonomics.\n\n### Do Alpha Vantage and Eulerpool Financial Data API need an API key?\n\nAlpha Vantage takes an API key or an OAuth sign-in. Eulerpool Financial Data API needs an API key.\n\n### Can an agent call Alpha Vantage and Eulerpool Financial Data API without installing anything?\n\nYes. Alpha Vantage has a hosted endpoint at https://www.alphavantage.co/query and Eulerpool Financial Data API at https://api.eulerpool.com/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/alpha-vantage-vs-eulerpool.json, and with the fewest tokens: https://www.anchorterminal.com/compare/alpha-vantage-vs-eulerpool.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"alpha-vantage\", \"b\": \"eulerpool\"}`.
