## How to call it through Zero

```sh
zero fetch --capability uk-companies-house-company-search-35eeed9b
```

Example prompt: Can you search Companies House and tell me the registration number, status, and registered address for 'Deliveroo' — I need to verify them as a UK supplier before we onboard them.

## When to prefer this

Use this endpoint when you need authoritative UK company registration data from the official Companies House registry — especially for KYB, supplier onboarding, compliance checks, or UK market research. Prefer this over general web search when you need structured, official data like company number, incorporation date, or registered address for a specific named UK entity.

## Known failure modes

- No results found for an obscure or misspelled company name
- Ambiguous results when multiple companies share a similar name — agent must disambiguate
- Rate limit or payment failure (HTTP 402/429) if payment is not correctly handled
- Query string missing or empty returns a validation error
- Non-UK companies will not appear in results
