## 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 uk-companies-house-lookup-a5cce67a
```

Example prompt: Can you look up the Companies House profile for Monzo Bank Limited — company number 09446231 — and tell me who the current officers are, whether it has any charges, and its registered office address?

## When to prefer this

Use this endpoint when you need authoritative UK company data sourced directly from Companies House public records — particularly for due diligence, KYB (know your business) verification, officer lookups, or confirming a company's active status and registered details. Prefer this over generic web search when you need structured, machine-readable corporate data with a verifiable official source.

## Known failure modes

- Company number not found returns empty results or total:0
- Invalid company number format returns an error or no match
- Name search with no matches returns empty items array
- Rate limiting or payment failure returns 402 or error response
- Ambiguous company name returns multiple results requiring disambiguation

## How this service works

Official UK company registry (Companies House). Two modes: pass query to search companies by name (returns company number, name, status, type, incorporation date, address), or pass companyNumber for the full registry profile — legal name, status, company type, jurisdiction, incorporation/cessation dates, SIC activity codes, registered office address, accounts (next due, last made-up-to), confirmation-statement due date, charges and insolvency flags, previous names, and the officers list (name, role, appointed/resigned dates, nationality, occupation). Free, Open Government Licence (commercial use permitted). The authoritative UK-company KYB lookup — complements business.lei (GLEIF) and business.br-cnpj (Brazil).

## Output

Returns a structured company profile including company name, type (e.g. ltd), status (active/dissolved), registered office address, list of officers with roles/nationalities/appointment dates, SIC codes, charges flag, insolvency history flag, incorporation date, accounts filing dates, jurisdiction, previous names, and the data source attribution from Companies House.
