Set up a Companies House account

To be able to explore and perform tests with the Companies House API, you need to register a user account with Companies House, and then generate an API key for use in each API request.

Explore the API

Each Companies House API reference page contains an embedded "explorer" that allows the reader to try out the service in-situ, without having to write any client code at all.
