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
A JSON object containing the company's CIK, an as-of timestamp, the count of matched filings, and an array of filing rows each with accession number, form type, filed date, SEC URL, item codes, description, and report date. Also includes a coverage_note explaining how far back the SEC's recent window reaches for that filer.
Example use cases
Track executive changes at a company
“Show me all 8-K filings for Tesla where item code 5.02 was reported — officer or director changes — going back to January 2022.”
Monitor earnings announcement filings
“Get the last 50 8-Ks filed by Microsoft with item code 2.02 so I can see every earnings release they've disclosed to the SEC.”
Screen for bankruptcy-related 8-Ks
“Pull 8-K filings for CIK 0000320193 that include item code 1.03 since 2024 — I want to see any bankruptcy or receivership disclosures.”
Technical details
Endpoint
GEThttps://answerpool.io/v1/sec/8k/historyWhen to prefer
Choose this endpoint when you need a company's 8-K history pre-filtered by SEC item codes without manually paginating EDGAR submissions and mapping item codes yourself. It is the right choice when you want event-specific filings (e.g. only officer changes or earnings) for a given ticker or CIK, especially when filtering by date range. Prefer it over general EDGAR submission APIs that return all form types and require client-side filtering.
Side effects
- Invalid or unknown ticker symbol returns empty filings array
- CIK format mismatch (non-numeric or too long) fails schema validation
- Item code filter returns no results if the company has never filed that item type
- Since date in wrong format (not YYYY-MM-DD) fails validation
- Coverage note may indicate limited historical window for some filers
- Limit exceeding 500 is rejected by schema
