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 with the company's CIK, fiscal year end (month-day string), the date of the last 10-K filed, the date of the last 10-Q filed, an array of recent 10-Q filing dates, a naive estimate for the next expected 10-Q date, a naive estimate for the next expected 10-K date, and an as-of timestamp. Includes a note that expected dates are estimates from historical cadence and a disclaimer that the data is derived from public SEC EDGAR filings and is not investment advice.
Example use cases
Monitoring next earnings filing window
“I'm tracking Netflix — can you pull their filing calendar so I know roughly when their next 10-Q is expected to drop and set up an alert window around that date?”
Confirming fiscal year end for a company
“What's the fiscal year end for Walmart? I need it for a financial model I'm building and want to confirm it from their actual SEC filings.”
Checking last 10-K date before analysis
“When did Alphabet last file their 10-K annual report with the SEC? I want to make sure my data is referencing the most recent annual filing.”
Technical details
Endpoint
GEThttps://answerpool.io/v1/sec/calendarWhen to prefer
Use this endpoint when you need a quick, pre-derived summary of a company's SEC reporting cadence without parsing raw EDGAR filings yourself. It is ideal for scheduling monitoring windows, confirming fiscal year ends, or checking when annual/quarterly reports were last filed. Prefer this over raw EDGAR queries when you only need cadence metadata and not the filing content itself. It complements the AnswerPool Filing Cadence endpoint (year-by-year counts) by providing absolute dates and forward-looking estimates.
Side effects
- Neither ticker nor CIK provided — returns error requiring at least one identifier
- Unknown ticker or CIK not found in EDGAR — returns null dates or empty response
- Company has irregular filing history — naive cadence estimates may be inaccurate or null
- Network timeout or upstream EDGAR unavailability — may return 5xx error
- Invalid CIK format (non-numeric or too long) — schema validation error
