## 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 form-4-insider-trades-7e4774e1
```

Example prompt: Pull the most recent SEC Form 4 insider trade filings for Tesla (TSLA) from the last 30 days, sorted by filing date descending, and show me up to 50 results.

## When to prefer this

Use this endpoint when you need structured, filterable access to SEC Form 4 insider ownership change filings — especially when filtering by ticker, CIK, or date range. Prefer this over general SEC EDGAR search when you need clean, machine-readable data with consistent pagination and sorting. Choose this over Form 3 filings when you need changes in ownership rather than initial ownership statements.

## Known failure modes

- Invalid date format returns a 400 error — dates must be YYYY-MM-DD
- Unknown or invalid CIK returns empty results rather than an error
- Requesting limit above 10,000 returns a validation error
- Malformed ticker symbol may return no results if not matched in EDGAR data
- Rate limiting or payment failure for x402 micropayment may block the request
