## 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 sirenic-uk-company-officers-0553ccdb
```

Example prompt: Who are the current directors and secretaries of UK company number 00102498? I need their roles, appointment dates, nationalities, occupations, countries of residence, and birth months from the official Companies House register.

## When to prefer this

Choose this endpoint when you need authoritative, live UK company officer data directly from the official Companies House register — especially for due diligence, KYC, compliance checks, or contract verification. It is GDPR-compliant (no correspondence addresses), pay-per-use at $0.01/call, and covers all UK company types including NI and SC numbers. Prefer it over web scraping or third-party aggregators when data freshness and official provenance matter.

## Known failure modes

- Unknown or invalid company number returns 404 and cancels payment
- Missing or invalid API key (CPH_UK) returns 503 (fail-closed)
- Malformed company number (missing leading zeros) may return 404
- Company with no officers on record may return an empty list
- Rate limiting or upstream Companies House outage may cause 5xx errors

## How this service works

UK company officers live from Companies House, the official UK company registry, by company number (e.g. GB/00102498): active directors and secretaries with role, appointment date, nationality, occupation, country of residence and month+year of birth only — never a correspondence address (GDPR minimisation). Resigned-officer count included. Built for KYB and due diligence on director appointments and governance. Contains public sector information licensed under the Open Government Licence v3.0.

## Output

A structured list of active officers (directors and secretaries) for the given UK company, each with: full name, role, appointment date, nationality, occupation, country of residence, and birth month+year. Also includes a count of resigned officers. Correspondence addresses are excluded per GDPR minimisation. Data is sourced from the official Companies House register under the Open Government Licence v3.0.
