## 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-uk-company-data-lookup-c949d319
```

Example prompt: Can you pull up the official Companies House record for Revolut Ltd — I need their registration number, current status, and registered address?

## When to prefer this

Choose this endpoint when you need authoritative, auditable UK company data sourced directly from Companies House, especially in compliance, due diligence, or contract verification contexts where a cryptographic audit trail matters. Prefer it over generic web search when you need structured, reliable fields like registration number, status, and registered address rather than unstructured web results.

## Known failure modes

- Company number not found — invalid or non-existent registration number returns an error
- Company name ambiguous — multiple matches may require a more specific query or numeric company number
- Rate limiting or payment failure — x402 micropayment not processed correctly
- Malformed company number — must be exactly 8 digits or a valid name string
- Stale data — Companies House data may lag real-time filings by days
