Api Endpoint

Eckari

Search the UK Companies House register by name or keyword and return matching companies with company number, register status and a derived is_active, type, incorporation and cessation dates and the register's one-line address snippet. Use this first when you only have a name, then call the per-company capabilities with the returned company_number. Ordering is the register's own, echoed as match_rank — a position, not a relevance score. Use when: Look up a UK company by name.
