## How to call it through Zero

```sh
zero fetch --capability uk-company-check-e58348fe
```

Example prompt: Can you check the Companies House status of UK company number 12345678 — I need to know if it's still active, whether its accounts are overdue, and if there are any insolvency or charges flags on it?

## When to prefer this

Use this endpoint when you need authoritative, real-time company-level facts from the official UK Companies House register, especially for supplier vetting, sales research, or compliance checks on UK-registered entities. Prefer this over general web search when you need structured, reliable data fields (status, incorporation date, SIC codes, charges) rather than unstructured public information.

## Known failure modes

- Invalid or non-existent company number returns a not-found error
- Malformed company number (wrong length or format) returns a validation error
- Companies House API unavailability may result in a timeout or 503 response
- Company number for a Scottish or foreign-registered entity may return incomplete or no data

## How this service works

Give a company number; get its status, type, incorporation date, SIC codes, registered office, whether accounts or the confirmation statement are overdue, insolvency and charges flags, and the number of active officers.
