## 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 uk-company-kyb-verdict-api-x-402-online-5eb611d0
```

Example prompt: Run a full KYB check on Revolut Ltd — I need their company status, whether they're up to date on filings and accounts, any insolvency history, current directors, and beneficial owners. Search by company name.

## When to prefer this

Choose this endpoint when you need a single-call comprehensive KYB verdict for a UK company rather than making multiple separate calls for status, officers, PSCs, and filing compliance. Ideal for onboarding workflows, AML screening, and supplier due diligence where speed and completeness matter. Prefer this over sibling endpoints (individual officer, PSC, or profile lookups) when you want the aggregated verdict in one step.

## Known failure modes

- Company not found by name or number — returns empty or 404-style error
- Ambiguous company name matches multiple entities — may return first match or require company number
- Companies House API unavailable — upstream dependency failure
- Invalid company number format — returns validation error
- Rate limiting or payment failure — 402 payment required not fulfilled
