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**CoinDesk Data API.** Official OpenAPI 3.0.3 document at data-api.coindesk.com/info/v1/openapi, with enums, examples and error responses from 400 to 503. No free or trial access since 2026-05-21, and no x402, so a person has to buy a plan before an agent gets data.\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### CoinDesk Data API\n\n1. Read the OpenAPI at `https://data-api.coindesk.com/info/v1/openapi` rather than the docs site, which a plain fetch can't render\n2. Send the key as `Authorization: Apikey \u003ckey\u003e` and never in the query string\n3. Use `groups` to ask for only the field groups you need on tick endpoints\n4. Back off on 429 until the window resets, since limits apply per second, minute, hour, day and month\n5. For reference prices, call the CADLI or CCIX index endpoints rather than one exchange's spot tick\n\n## Questions\n\n### Which is better for AI agents, Alpha Vantage or CoinDesk Data API?\n\nCoinDesk Data API scores 46.6 (D) on agent readiness against Alpha Vantage's 41.3 (E), and leads in 5 of 7 scored categories. Alpha Vantage leads on payments \u0026 pricing and maintenance \u0026 community.\n\n### Do Alpha Vantage and CoinDesk Data API need an API key?\n\nAlpha Vantage takes an API key or an OAuth sign-in. CoinDesk Data API needs an API key.\n\n### Can an agent call Alpha Vantage and CoinDesk Data API without installing anything?\n\nYes. Alpha Vantage has a hosted endpoint at https://www.alphavantage.co/query and CoinDesk Data API at https://data-api.coindesk.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/alpha-vantage-vs-coindesk-data-api.json, and with the fewest tokens: https://www.anchorterminal.com/compare/alpha-vantage-vs-coindesk-data-api.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"alpha-vantage\", \"b\": \"coindesk-data-api\"}`.
