## 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`):

Example prompt: Can you pull the full company profile for UK company number 07495895 from Companies House — I need their registered address, status, and incorporation date.

## When to prefer this

Choose this endpoint when you need live, structured UK company data from the authoritative Companies House registry for a known company number. It is ideal for KYB (Know Your Business) workflows, due diligence pipelines, onboarding automation, or any agent that needs to verify or enrich UK business information in real time. Prefer this over web scraping or static databases when freshness and official provenance are required. It is specifically scoped to UK-registered companies and requires a company number as input rather than a name search.

## Known failure modes

- Invalid or non-existent company number returns an error or empty data object
- Companies House registry temporarily unavailable causes upstream timeout
- Dissolved or struck-off companies may return partial data with warnings
- Malformed company number format may result in a 400-level error
- Rate limiting or payment failure via x402 may block the request
