## 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 strale-beneficial-ownership-lookup-b0f6b67f -d '<json body>'
```

Example prompt: Who are the beneficial owners of Siemens AG in Germany? I need this for a KYC compliance check — the company registration number is HRB 248136.

## When to prefer this

Choose this endpoint when you need structured, independently tested beneficial ownership data across 27 countries with a cryptographic audit trail for compliance purposes (KYC, AML, due diligence). Prefer it over general web search when you need machine-readable ownership records with verifiable provenance, or when operating in a regulated context where an audit record is required.

## Known failure modes

- Company not found in the registry for the specified jurisdiction — returns empty or no-match result
- Invalid or unrecognized company registration number — returns validation error
- Unsupported jurisdiction — country not covered among the 27 supported countries
- Ambiguous company name with multiple matches — may return multiple candidates or require disambiguation
- Payment failure via x402 micropayment — call not executed
- Rate limiting or quota exceeded — HTTP 429 response
