## 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 api-strale-io-c622c1a7 -d '<json body>'
```

Example prompt: Who are the ultimate beneficial owners of Accenture Holdings UK Ltd — give me each person's name, ownership percentage, and the full ownership chain. The jurisdiction is GB.

## When to prefer this

Choose this endpoint when you need to identify the real human individuals behind a company for KYC, AML, or corporate due diligence purposes — especially for UK-registered companies where Companies House and OpenOwnership data is available. Prefer this over generic company lookup endpoints when the specific goal is tracing ultimate control rather than just registered corporate details.

## Known failure modes

- Company not found in registry — returns empty or null UBO list
- Jurisdiction not supported — non-UK companies may have limited data coverage
- Ambiguous company name with multiple matches — may require company_number to disambiguate
- Ownership data unavailable or not disclosed in the registry — partial results returned
- Invalid ISO country code returns a validation error
