## 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 market-intelligence-api-sec-form-144-proposed-insider-sales-4da8c81c
```

Example prompt: Pull the SEC Form 144 insider sale notices for NVDA from the past 30 days — I want to see who's planning to sell, how much, and their relationship to the company.

## When to prefer this

Choose this endpoint when you need advance visibility into planned insider stock sales via SEC Form 144 filings for a specific US-listed company. It is distinct from Form 4 insider transaction endpoints (which report completed trades) — Form 144 captures proposed future sales before execution, giving earlier signal. Prefer this over general insider-trading APIs when you specifically need pre-sale disclosure data for officers, directors, or 10%+ shareholders.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- days parameter out of range (outside 1–365) returns a validation error
- No Form 144 filings exist for the symbol in the requested period — returns empty list
- Rate limit or payment failure (x402) blocks the response
- Ticker is not a US-listed equity (e.g. a crypto symbol) may return no results or an error

## Output
