Company House Search API

POST
/company_house_search
LIVE

Searches the UK Companies House register for a company by name or company number. The endpoint auto-detects whether the input is a company number (for example 12345678, SC123456, NI012345, FC012345, OC123456) or a free-form name, then dispatches the right search. Returns the company number, registered name, status, type, incorporation date and registered office address.
