UK Companies House

Search and inspect the official UK companies register: company profiles, directors and secretaries, filing history. Free public API with a 600 requests / 5 minutes rate limit. The UK equivalent of the German Handelsregister.

Setup

Getting an API key: register a free account at https://developer.company-information.service.gov.uk → 'Manage applications' → 'Create an application' (pick Live or Test) → 'Create new key' → REST. Copy the generated key into COMPANIES_HOUSE_API_KEY.

Authentication quirk: Companies House uses HTTP Basic Auth where the API key is the username and the password is empty (the canonical curl shape is -u API_KEY:). This adapter mirrors that — leave the password configuration empty.

Company numbers: always 8 characters, zero-padded (e.g. 00006400 not 6400). The search endpoint returns matches with the canonical number you can feed into the other tools.
