What is a company registry API?+
A company registry API returns official company records (name, number, status, address, officers and filings) from government business registers as structured data.
Does it cover Companies House?+
Yes. UK Companies House search, company profiles, officers and filings are covered, with SIRENE, Brreg, CNPJ, GLEIF and other registers.
Is there a free tier?+
Yes. Every account gets 1,000 free credits each month, no card needed. Paid calls start at $1 per 1,000.
Why not use each government API directly?+
