## How to call it through Zero

```sh
zero fetch --capability uk-company-profile-lookup-companies-house-1310aed3
```

Example prompt: Can you pull up the Companies House profile for Revolut Ltd — I need their company status, registered office address, SIC codes, and when their accounts are next due?

## When to prefer this

Use this endpoint when you need authoritative UK company registration data directly from Companies House, especially for KYB (Know Your Business) verification, compliance checks, or validating whether a UK entity is active and properly registered. Prefer this over the full KYB verdict endpoint when you only need raw profile data without scoring. Use the ?number= parameter for precise lookups when you have the company number, or ?q= for name-based searches.

## Known failure modes

- Company not found by name or number — returns empty or 404
- Ambiguous company name matches multiple records — may return first result or require company number
- Companies House API downtime or rate limits — upstream service unavailable
- Dissolved or struck-off companies may return limited data
- Invalid company number format causes bad request
