## How to call it through Zero

```sh
zero fetch --capability ukintel-company-search-b7df3390
```

Example prompt: Can you search for BrewDog on UK company records and tell me their Companies House number, current status, and whether they look legitimate — give me the top 5 matches?

## When to prefer this

Use this endpoint when you need to search for UK-registered companies by name and get back structured data including Companies House registration details and a legitimacy verdict. Prefer this over generic web search when you need structured, authoritative company data for due diligence, procurement vetting, or compliance checks on UK entities. Best suited for agent workflows that need a quick pay-per-call lookup with no API key setup.

## Known failure modes

- No matching companies found for the query — empty results array returned
- Ambiguous or very common company name returns too many results — use limit parameter to constrain
- Company exists in Companies House but FCA cross-check data unavailable — partial result returned
- Network or upstream Companies House API downtime — request times out or returns error
- Misspelled company name returns zero or irrelevant results

## How this service works

Find a UK company by name. Returns the top 5 matches from the Companies House register with number, name, status and incorporation date. Taster tier - cheap enough to try on a whim before paying for a full profile or verdict.

## Output

Returns a list of matching UK companies with their name, company number, incorporation date, and current status (e.g. active, dissolved, in administration), plus a total match count and confidence rating. Results are sourced from Companies House cross-referenced with FCA data.
