## 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 sec-filings-index-814dc111
```

Example prompt: Pull the 10 most recent 10-K annual filings for Tesla (ticker: TSLA) from the SEC EDGAR index, sorted by filing date descending.

## When to prefer this

Choose this endpoint when you need to discover and index SEC filings by company (via ticker or CIK) or form type, especially when you want filterable, sortable metadata including filing dates and document links. Prefer this over direct SEC EDGAR queries when you need a clean, agent-friendly API with structured filtering and x402 micropayment support. Best for agents that need to enumerate or monitor filing activity rather than parse the full document content.

## Known failure modes

- Invalid or unknown ticker symbol returns empty results
- Malformed CIK format causes validation error
- Requesting more than 10,000 results exceeds maximum limit and returns error
- Invalid form_type value returns no matching filings
- Date filter syntax errors return 400 bad request
- Rate limiting or payment failure returns 402 or 429 error
