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 structured list of all subsidiaries extracted from the company's most recent Exhibit 21, including each subsidiary's name and jurisdiction of incorporation. Also returns the parent company's CIK, full name, filing accession number, filing date, an as-of date, a direct URL to the source SEC exhibit for verification, a total count, and any parsing notes or disclaimers.
Example use cases
Due diligence corporate entity mapping
“I'm doing due diligence on Alphabet — ticker GOOGL — and need a complete list of all its subsidiaries with their jurisdictions from the latest 10-K Exhibit 21. Can you pull that for me?”
Regulatory compliance jurisdiction audit
“For our compliance audit, can you get every subsidiary of JPMorgan Chase (ticker JPM) and which countries or states they're incorporated in, straight from their most recent annual report filing?”
Competitive intelligence subsidiary count
“How many subsidiaries does Tesla have according to their latest Exhibit 21? List them all with jurisdictions so I can map out their international presence.”
Technical details
Endpoint
GEThttps://answerpool.io/v1/graph/subsidiariesWhen to prefer
Use this endpoint when you need to rapidly enumerate the legal subsidiaries of any SEC-reporting public company without manually locating and parsing EDGAR filings. It is the best choice for due diligence workflows, compliance audits, corporate structure mapping, or competitive research where the source of truth is the company's own SEC-filed Exhibit 21. Prefer it over general EDGAR search when you want structured, pre-parsed subsidiary rows rather than raw filing documents.
Side effects
- Company not found — invalid ticker or CIK returns an error or empty result
- Company has not filed an Exhibit 21 — some filers are exempt and the endpoint may return null or a note
- Heuristic parsing errors — subsidiary names or jurisdictions may be mis-extracted from non-standard exhibit formats
- Stale data — if the latest annual report is several months old, the subsidiary list may not reflect recent M&A
- Rate limiting or payment failure — x402 payment not processed results in a 402 or auth error
