## 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-schedule-13d-13g-beneficial-ownership-filings-c4f76775
```

Example prompt: Pull all Schedule 13D and 13G beneficial-ownership filings for Tesla (ticker TSLA) from the past two years — I want to see every major stakeholder who disclosed a position over 5% and any amendments they filed.

## When to prefer this

Use this endpoint when you specifically need Schedule 13D or 13G beneficial-ownership disclosures — i.e., who owns more than 5% of an issuer and any amendments to those positions. Prefer this over general filing history endpoints when the focus is on large shareholders, activist investors, or ownership transparency. It is more targeted than a full EDGAR filing search and returns normalized ownership data rather than raw document links.

## Known failure modes

- Invalid or unrecognized ticker returns no results or an error
- CIK not found in EDGAR returns empty result set
- Lookback window too narrow yields zero filings for infrequently reported issuers
- Rate limit or payment failure returns 402 Payment Required
- Requesting both ticker and CIK simultaneously may cause ambiguous resolution
