## 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-3-insider-filings-7122eb3e
```

Example prompt: Can you pull the most recent SEC Form 3 initial ownership filings for Tesla (ticker: TSLA) from the last 30 days, sorted by filing date descending?

## When to prefer this

Use this endpoint when you need to identify when corporate insiders (directors, officers, or 10%+ shareholders) first disclosed a beneficial ownership position in a company via SEC Form 3 filings. Prefer this over Form 4 when you specifically want initial ownership statements rather than changes in ownership. Ideal for monitoring new insider entries, corporate governance research, and compliance tracking.

## Known failure modes

- No filings found matching the specified filters (empty result set)
- Invalid CIK format (must be 10 digits, zero-padded)
- Invalid date format (must be YYYY-MM-DD)
- Limit exceeds maximum of 10,000
- Invalid sort column or direction specified
- Payment failure for the $0.01 USDC per call fee

## How this service works

SEC Form 3 filings reporting initial statements of beneficial ownership of securities. Filed by corporate insiders (directors, officers, and 10%+ shareholders) when they first acquire a position. Can't find what you're looking for? POST feedback to /feedback, no charge.

## Output

Returns a list of SEC Form 3 filing records including filing date, form type (3 or 3/A), issuer company details, reporting owner identity and CIK, and beneficial ownership information. Results can be filtered by ticker, issuer CIK, owner CIK, filing date range, and form type, and sorted and paginated as needed.
