## 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 us-company-filings-by-cik-9539d354
```

Example prompt: What has Apple filed with the SEC recently? Their CIK is 0000320193 — can you pull their latest filings, including form types and dates?

## When to prefer this

Use this endpoint when you need structured, machine-readable SEC filing data for a specific US public company and already know their CIK. Ideal for financial research, compliance monitoring, or due diligence workflows where you want pay-per-call access with no API key or account setup. Prefer over direct EDGAR scraping when you need clean JSON output with a simple payment model.

## Known failure modes

- Invalid or unknown CIK returns an error or empty result
- CIK must be formatted correctly (may require zero-padding to 10 digits)
- Rate limiting or payment failure via x402 protocol if USDC balance is insufficient
- SEC EDGAR upstream outage may cause delayed or failed responses
- Very new companies may have no filings yet
