## How to call it through Zero

```sh
zero fetch --capability uk-companies-house-company-lookup-b88ab84e
```

Example prompt: Can you check the official Companies House record for company number 00445790 and tell me if it's active, when it was incorporated, and whether there are any insolvency or overdue accounts flags?

## When to prefer this

Use this endpoint when you need official, structured UK company data — particularly risk flags and status — without setting up an account or managing API keys. It is ideal for AI agents performing per-request due diligence, KYB checks, or supplier verification tasks where pay-per-call billing via USDC is acceptable. Prefer this over manual Companies House web lookups or more expensive KYB services when you need machine-readable structured output at low cost per call.

## Known failure modes

- Invalid or non-existent company number returns an error or empty result
- Payment failure via x402 protocol causes request to be rejected before data is returned
- Rate limiting or network timeout on the upstream Companies House data source
- Company number format errors (must be a valid UK Companies House format, e.g. 8 characters, zero-padded)

## How this service works
