## When to prefer this

Use this endpoint when you need authoritative, auditable officer data for UK-registered companies directly from Companies House. Prefer it over generic business data APIs when you need UK-specific corporate governance data with a cryptographic audit trail, or when compliance and trust verification are requirements. Ideal for KYC, AML, due diligence, or contract verification workflows involving UK entities.

## Known failure modes

- Company not found — invalid or unrecognised company name/number returns empty results or error
- Ambiguous company name matching multiple entities — may require company_number for precision
- Companies House API downtime or rate limiting causing upstream errors
- Dissolved or struck-off companies may return limited or no active officer data
- Missing required query parameters returns validation error
