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Returns a JSON object containing the company's name, CIK, an as-of timestamp, a current stage label (e.g. 'effective', 'withdrawn', 'filed'), a count of total events, and an ordered array of lifecycle events each with form type (e.g. S-1, S-1/A, 424B4), filing date, accession number, and a direct EDGAR document URL. Also includes a method_id and regulatory disclaimer.
Example use cases
Check if startup IPO is effective
“Can you look up the IPO lifecycle for Klaviyo on SEC EDGAR and tell me whether their registration has been declared effective yet, and show me all the filings in order?”
Research company's IPO withdrawal
“I heard WeWork withdrew an IPO registration at some point — can you pull their complete SEC IPO filing history so I can see every step they took and confirm whether they actually withdrew?”
Track amendment history before listing
“I'm researching Arm Holdings' path to going public — show me every S-1 and amendment they filed with the SEC, in chronological order, along with their current IPO stage.”
Technical details
Endpoint
GEThttps://answerpool.io/v1/ipo/companyWhen to prefer
Use this endpoint when you need a structured, chronologically ordered view of a single company's complete SEC IPO filing lifecycle, including the current stage label derived from heuristic rules applied to EDGAR data. Prefer it over raw EDGAR searches when you want pre-merged, labeled results covering 2021 and beyond without manually parsing EDGAR full-text. Best for due diligence research, competitive intelligence on IPO timelines, or monitoring whether a specific company's offering has gone effective or been withdrawn.
Side effects
- No matching company found for name substring — returns empty or null result
- Ambiguous company name matching multiple registrants — may return first match or require CIK to disambiguate
- CIK not found in EDGAR — returns empty events array
- Company has no IPO-related filings — empty events list with no meaningful stage
- Rate limiting or payment failure at $0.05 per call — 402 payment required error
- Invalid CIK format (non-numeric or too long) — schema validation error
- Limit parameter out of range (below 1 or above 500) — validation error
