## 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-144-intelligence-insider-transaction-lookback-72ec347f
```

Example prompt: Pull the Form 144 insider transaction intel for NVDA over the last 60 days — I want to see if any insiders have filed notices of intended stock sales.

## When to prefer this

Use this endpoint when you need SEC Form 144 data specifically — planned insider stock sale disclosures — for a US-listed equity. Prefer this over general insider trading endpoints when you specifically need pre-sale notification filings rather than completed transaction reports (Form 4). Ideal for compliance research, equity analysis, or monitoring insider selling intentions at micro-cost via x402 with no account required.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Lookback window exceeding 180 days is rejected or capped
- No Form 144 filings exist for the ticker in the requested window returns empty dataset
- Payment failure or insufficient USDC balance blocks the request
- Rate limiting or network error from upstream SEC data source

## How this service works

Retrieves SEC Form 144 planned insider sale filings for a US public company — earlier signal than Form 4 (post-trade). Returns seller name, role, shares planned for sale, market value, approximate sale date, and acquisition type (RSU, open market, etc.).

## Output

Returns SEC Form 144 filing data for the requested ticker, including insider names, intended sale amounts, dates of filing, and related transaction details covering the specified lookback period (default 30 days, max 180 days).
