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.\n\n## Score by category\n\n| Category | Weight | Alpha Vantage | Financial Modeling Prep | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 30 | 50 | Financial Modeling Prep +20 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 46 | 61 | Financial Modeling Prep +15 |\n| Agent ergonomics | 13% (16.2 this run) | 54 | 59 | Financial Modeling Prep +5 |\n| Security \u0026 auth | 14% (17.5 this run) | 32 | 30 | Alpha Vantage +2 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 30 | 30 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 63 | 60 | Alpha Vantage +3 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 50 | 57 | Financial Modeling Prep +7 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **41.5 · E** | **48.7 · D** | |\n\n## Facts side by side\n\n| Fact | Alpha Vantage | Financial Modeling Prep |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Alpha Vantage Inc. | Financial Modeling Prep |\n| Hosted endpoint | `https://www.alphavantage.co/query` | `https://financialmodelingprep.com/stable` |\n| Transports | HTTP, Streamable HTTP, stdio | HTTP, Streamable HTTP |\n| Auth | OAuth or key | API key |\n| Pricing | Freemium | Freemium |\n| x402 | no | no |\n| Licence | Proprietary service under Alpha Vantage's Terms of Service.

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**Financial Modeling Prep.** About 199 stable REST endpoints with Markdown docs for agents, a dated changelog and a free key at 250 calls a day. The one key travels in the query string on the documented MCP address, error responses and 429 handling are undocumented, the status history could not be read, and personal plans forbid any company use.\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### Financial Modeling Prep\n\n1. Send the key as an `apikey` header, not in the URL, and treat the MCP `?apikey=` address as a secret\n2. Use the /stable paths from api-docs.md; /api/v3 and /v4 are discontinued even though the FAQ still shows a v3 example\n3. On the free plan expect 5 results and page 0 on many list endpoints; read pricing.md before planning a crawl\n4. A missing or wrong key returns HTTP 401 with an `Error Message` field; stop and ask the user rather than retry\n5. Do not display or pass on the data in a product; personal plans forbid it\n\n## Questions\n\n### Which is better for AI agents, Alpha Vantage or Financial Modeling Prep?\n\nFinancial Modeling Prep scores 48.7 (D) on agent readiness against Alpha Vantage's 41.5 (E), and leads in 4 of 7 scored categories.\n\n### Do Alpha Vantage and Financial Modeling Prep need an API key?\n\nAlpha Vantage takes an API key or an OAuth sign-in.
