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-sec-filing-history-495d8f6a
```

Example prompt: Pull the complete SEC filing history for Apple (CIK 0000320193) from AnswerPool's historical index — filter it down to 10-K and 10-Q forms so I can see their annual and quarterly reports going back as far as the index covers.

## When to prefer this

Choose this endpoint when you need a filer's deep historical filing record beyond what EDGAR's recent feed covers, or when paginating EDGAR directly is too slow. Ideal for due diligence workflows, compliance audits, and multi-year disclosure analysis where you need accession numbers, form types, and direct document URLs in one structured response. Prefer it over the 'recent' shard when you need coverage beyond the last few filings.

## Known failure modes

- Invalid or unknown CIK returns empty results or 404
- Form type filter typo returns no results silently
- Date range outside index coverage window returns empty filings array
- Rate limiting or payment failure returns 402 or 429 error
- Index lag means very recent filings (past few days) may not appear

## 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 filer's CIK, an as-of timestamp, total filing count, index coverage window (index_from and index_to dates), and an array of individual filing records each with accession number, form type, filed date, company name, and direct SEC Archives URL.
