## 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-by-reporting-owner-cik-92cad429
```

Example prompt: Pull all SEC Form 4 insider trades filed by the reporting owner with CIK 0001234567 — I want to see every company they've transacted in and what they bought or sold.

## When to prefer this

Use this endpoint when you need to track a specific individual or entity (serial founder, activist investor, fund principal) across all companies they have filed Form 4 reports for, rather than looking up insiders by issuer. Ideal for profiling a single insider's cross-company trading behavior rather than all insiders at one company.

## Known failure modes

- Invalid or non-existent CIK returns a 404 or empty result set
- CIK belongs to an issuer rather than a reporting owner — no Form 4 data returned
- Reporting owner has no Form 4 filings on record — empty response
- Rate limiting or payment failure results in 402 response
- EDGAR data lag may mean very recent filings are not yet reflected

## How this service works

One reporting owner's SEC Form 4 transactions across every issuer they file for — track serial founders, activists, and fund principals

## Output

A list of SEC Form 4 transactions filed by the specified reporting owner CIK, spanning all issuers they have reported for — including issuer names, transaction dates, share counts, transaction types (buy/sell/grant), and ownership details across their full filing history.
