## How to call it through Zero

```sh
zero fetch --capability stablefinance-dev-ec1ba8d1
```

## When to prefer this

Use this endpoint when you need SEC Form 4 insider transaction data for a specific publicly traded company, especially when you want to filter by date range, insider name, or transaction type. Prefer this over generic financial data endpoints when the specific need is regulatory insider trading disclosures.

## Known failure modes

- Missing required 'ticker' parameter returns a validation error
- Invalid date format (not YYYY-MM-DD) causes a 400 error
- Ticker with no Form 4 filings returns an empty insider_trades array
- Limit exceeding 1000 causes a validation error
- Invalid transaction_type value may return no results or an error
