## 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 lookup-bustercall-workers-dev-a50cf18d -d '<json body>'
```

Example prompt: Can you pull the most recent 8-K filings from SEC so I can see which public companies have disclosed material events lately?

## When to prefer this

Use this endpoint when an agent needs programmatic access to recent SEC 8-K filings in structured JSON format, particularly in automated financial research, compliance monitoring, or event-driven trading workflows. Prefer over scraping SEC EDGAR directly when a paid, structured JSON response is needed quickly.

## Known failure modes

- Payment not provided or insufficient USDC — returns 402 Payment Required
- No recent 8-K filings found for the given filters — returns empty array
- Upstream SEC data source unavailable — returns 503 or error object
- Invalid request body format — returns 400 Bad Request

## Output

A JSON array of recent 8-K filings, likely including company names, filing dates, CIK numbers, and links or summaries of the filed material event disclosures.
