How this service works
AnswerPool turns SEC EDGAR, the Federal Register, USAspending, NIH, BLS and OpenAlex into structured JSON answers that AI agents and developers fetch in one call. 69 endpoints free, no account; derived analyses $0.02–$0.05 per call by card credits or USDC (x402). MCP server, full provenance.
Output
Returns a JSON object containing the CIK, accession number, as-of timestamp, total document count, and an array of documents each with its filename, MIME/type, byte size, and direct SEC.gov download URL.
Example use cases
Fetch exhibit from 10-K filing
“I need the direct download URL for the EX-21 subsidiaries exhibit inside Apple's 10-K filing with accession number 0001437749-26-028920 — can you list all the documents so I can find it?”
Extract XBRL data file from annual report
“Pull up all the files inside SEC filing 0001193125-24-123456 for CIK 0000320193 and tell me which ones are the XBRL or XML documents so I can grab the structured data.”
Audit filing attachments for completeness
“List every document included in SEC filing accession number 0000950170-24-056789 — I want to see all the file names, types, and sizes to verify nothing is missing.”
Technical details
Endpoint
GEThttps://answerpool.io/v1/sec/filing/documentsWhen to prefer
Use this endpoint when you know a specific SEC accession number and need to programmatically access individual documents (exhibits, XBRL, XML, primary docs) without scraping the EDGAR HTML index page. Prefer this over full-text search endpoints when you already have the filing identifier and want direct download URLs for specific file types.
Side effects
- Invalid or malformed accession number returns an error or empty document list
- CIK mismatch with accession number may return no results
- Filing not yet indexed by EDGAR returns empty or stale results
- Network timeout if SEC EDGAR is slow to respond
- Accession number for a very old filing may not have full document metadata
