## 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 stratalize-sec-beneficial-ownership-13d-13g-activist-signal-c372ef21
```

Example prompt: Pull the SEC 13D and 13G beneficial ownership filings for AAPL and tell me whether any 5%+ shareholders are classified as activists.

## When to prefer this

Use this endpoint when you need to identify activist vs. passive 5%+ shareholders in a public company, particularly when assessing shareholder activism risk, M&A vulnerability, or corporate governance dynamics. Prefer this over generic SEC filing search tools when you specifically need intent classification (activist vs. passive) derived from Schedule 13D vs. 13G distinctions with ML-based scoring. The cryptographic signing makes it suitable for compliance and audit workflows requiring verifiable provenance.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty filing set
- No 13D/13G filings on record for the ticker returns an empty result
- SEC EDGAR data lag may mean very recent filings are not yet reflected
- Payment failure (x402) results in 402 response before data is returned
- Network or upstream EDGAR outage may cause timeout or 5xx error
