## 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 x402stock-sec-form-3-initial-insider-holdings-b9b74609
```

Example prompt: Pull the last 10 SEC Form 3 initial insider ownership filings for NVDA — I want to see what shares and securities each new director or officer declared when they first joined.

## When to prefer this

Use this endpoint when you need the initial ownership baseline that an insider declared upon becoming a director, officer, or 10% shareholder — i.e., the starting point before any Form 4 transactions. It complements Form 4 data by establishing what insiders held at inception. Prefer this over general SEC filing endpoints when you specifically need Form 3 data rather than ongoing transaction history.

## Known failure modes

- Invalid or unknown ticker symbol returns an error or empty result set
- Ticker with no Form 3 filings on record returns an empty array
- Limit parameter outside allowed range (must be 1–25) returns a validation error
- SEC EDGAR source unavailability may cause delayed or failed responses
- Network or payment (x402/USDC) failure prevents the request from completing

## How this service works

Initial beneficial-ownership holdings parsed from SEC Form 3 filings, the first report an insider files on becoming a director, officer, or 10% holder. Each holding carries the security, shares owned, direct or indirect ownership, and derivative terms. Complements Form 4 transactions. ?limit= filings (default 5). Sourced from SEC EDGAR. From x402stock, a market & economic data API (x402, USDC).

## Output

A list of parsed Form 3 filings (up to the requested limit, default 5, max 25), each containing the reporting insider's identity, the security name, number of shares owned, whether ownership is direct or indirect, and any derivative instrument terms such as options or warrants. Data is sourced directly from SEC EDGAR.
