## 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 macaroon-network-companies-house-live-search-33d3f690 -d '<json body>'
```

Example prompt: Can you look up 'Rolls-Royce Holdings' on Companies House and tell me their company number, current status, registered address, and when they were incorporated?

## When to prefer this

Use this endpoint when you need live, authoritative UK company data directly from Companies House — particularly for due diligence, compliance checks, or verifying a company's legal existence and status. Prefer this over cached or third-party company databases when data freshness matters. It is specifically scoped to UK-registered companies; for US or international entities, use alternative registries.

## Known failure modes

- Company not found — returns empty results if no match exists on the register
- Ambiguous name returns multiple results — caller must disambiguate by company number
- Companies House API rate limiting or downtime — may return error or timeout
- Dissolved or struck-off companies may appear with limited metadata
- Input query too vague — broad searches may return many low-relevance results

## How this service works

Search current public UK company metadata from the official Companies House Public Data API. Returns a bounded normalized result with company identity, status, type, creation date, registered-address summary, official record link, retrieval time, and content hash.

## Output

Returns a normalized object containing: company name, company number, company status (e.g. active, dissolved), company type (e.g. ltd, plc), incorporation date, a summary of the registered address, a direct link to the official Companies House record, the retrieval timestamp, and a content hash for cache/integrity verification. Results are bounded to a set number of matches per query.
