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**SEC EDGAR APIs.** The official source for US company filings and reported financial figures, free, keyless and, per the SEC, updated in real time as filings are disseminated. Documentation is one page with no OpenAPI file, error reference or changelog, responses cannot be filtered or sized, and there is no status page, SLA or support for scripted access.\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### SEC EDGAR APIs\n\n1. Send a User-Agent naming the operator's organisation and a contact email address on every request. The SEC limits or blocks undeclared automated tools\n2. Stay under 10 requests a second in total across all machines. Over the limit, the IP address may be limited until the rate has stayed below the threshold for 10 minutes\n3. Pad the CIK to 10 digits with leading zeros in `submissions/CIK##########.json` and the XBRL paths. Find a CIK in `https://www.sec.gov/files/company_tickers.json`\n4. Prefer `api/xbrl/companyconcept/` for one figure. `companyfacts` returns every concept a company has reported, and `submissions` returns at least 1,000 filings in column arrays\n5. Read older filings from the extra files named in `filings.files`, and check a frame fact's own start and end dates, since frames align company periods to calendar quarters\n\n## Questions\n\n### Which is better for AI agents, Alpha Vantage or SEC EDGAR APIs?\n\nAlpha Vantage and SEC EDGAR APIs score within a point of each other on agent readiness, 41.3 (E) and 40.8 (E).
