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 timestamp (as_of), the lookback window in days, a count of matching filings, and an array of filing records each with accession number, CIK, company name, ticker, form type (RW or AW), filing date, and a direct SEC EDGAR URL. Also includes a method_id, an optional note, and a standard disclaimer that this is not investment advice.
Example use cases
Monitoring failed IPO pipeline
“Show me every company that pulled its SEC registration statement in the last 14 days — I want a list with company names, tickers if available, and links to the filings so I can track which deals fell apart.”
Weekly deal-withdrawal briefing
“Give me a weekly summary of withdrawn IPO registrations — fetch the last 7 days of RW and AW filings from AnswerPool and tell me how many deals were pulled and who they were.”
Research dead-deal trends over the past year
“I'm researching how many companies abandoned their registration statements over the past 365 days — can you pull the full list of withdrawn filings from AnswerPool, up to 100 results, and give me the company names, form types, and filing dates?”
Technical details
Endpoint
GEThttps://answerpool.io/v1/ipo/withdrawnWhen to prefer
Use this endpoint when you specifically need to track IPO or registration statement withdrawals (RW/AW form types) from SEC EDGAR in a single API call. It is the best choice for building dead-deal monitors, analyzing failed IPO pipelines, or identifying companies that abandoned public offering plans. Prefer this over general SEC EDGAR search when you want pre-filtered, recency-sorted withdrawal filings without needing to parse raw EDGAR full-text search results.
Side effects
- Invalid days parameter (outside 1–365 range) returns a validation error
- Invalid limit parameter (outside 1–100 range) returns a validation error
- Payment not provided or insufficient USDC results in a 402 Payment Required response
- No withdrawn filings in the requested window returns an empty filings array with count 0
- SEC EDGAR data source temporarily unavailable may return a service error
