# AnswerPool Filing Calendar

> AnswerPool Filing Calendar is a paid API for AI agents from answerpool.io, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Returns a public company's SEC filing cadence including fiscal year end, last 10-K/10-Q dates, recent quarterly dates, and naive next-report estimates derived from historical spacing.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability answerpool-filing-calendar-0c2e98ed
```

Example prompt: What's Apple's SEC filing calendar — when did they last file a 10-K and 10-Q, and when are the next ones expected? Use their ticker AAPL.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
