## 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 api-strale-io-e8aa5519
```

Example prompt: Who are the current and past directors of Rolls-Royce Holdings PLC? Look them up via Companies House and include their appointment and resignation dates.

## When to prefer this

Use this endpoint when you need structured officer data for a UK-registered company from the official Companies House registry, especially for due diligence, KYC checks, or compliance workflows. Prefer this over general web scraping when you need authoritative, structured appointment and resignation dates.

## Known failure modes

- Company not found — invalid or non-existent company name or number returns empty or error response
- Ambiguous company name matches multiple companies — may require company_number for precision
- Rate limiting or payment failure — returns 402 if payment not processed correctly
- Companies House API downtime — upstream service unavailability causes failure
