## 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-document-list-78a1d6d6
```

Example prompt: Can you list all the documents in Apple's SEC filing with accession number 0001437749-26-028920 — I need the direct URLs for each file, especially any XML or exhibit attachments.

## When to prefer this

Use this endpoint when you know a specific SEC accession number and need to programmatically access individual documents (exhibits, XBRL, XML, primary docs) without scraping the EDGAR HTML index page. Prefer this over full-text search endpoints when you already have the filing identifier and want direct download URLs for specific file types.

## Known failure modes

- Invalid or malformed accession number returns an error or empty document list
- CIK mismatch with accession number may return no results
- Filing not yet indexed by EDGAR returns empty or stale results
- Network timeout if SEC EDGAR is slow to respond
- Accession number for a very old filing may not have full document metadata

## 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 CIK, accession number, as-of timestamp, total document count, and an array of documents each with its filename, MIME/type, byte size, and direct SEC.gov download URL.
