Endpoint

Use this endpoint when you need to verify or look up a UK-registered business against the official Companies House register — ideal for KYB (Know Your Business) checks, compliance workflows, due diligence, or retrieving authoritative registered address and officer data. Prefer this over general web search when you need official, structured registry data.
