## 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-form-4-insider-trades-lookup-6ca5d9d9
```

Example prompt: Before I place a trade on TSLA, pull the SEC Form 4 insider trades for the last 90 days — I want to know if executives or directors are net buying or selling and what the overall signal looks like.

## When to prefer this

Choose this endpoint when you need to check whether company insiders (executives, directors, 10%+ owners) are buying or selling a US-listed stock before making a trading decision. It is purpose-built for SEC Form 4 data with pre-computed signals and 10b5-1 plan tagging, making it faster than parsing raw EDGAR filings yourself. Prefer it over generic news sentiment or analyst rating endpoints when you want regulated, disclosed insider activity as a trading signal.

## Known failure modes

- Invalid or non-existent ticker symbol returns an error or empty result
- Days parameter outside 1-365 range may be rejected or clamped
- No Form 4 filings in the look-back window returns empty trades list
- Rate limiting or payment failure returns 402 or 429 error
- Ticker for a non-US stock (e.g. foreign-listed) may return no SEC data

## How this service works

Use before trading a stock.
