What Is a KYC API?
A KYC (Know Your Customer) API lets you automatically verify company identity and legitimacy during onboarding - without manual checks or paperwork.
Instead of manually looking up company registrations, checking government databases, and cross-referencing addresses, a KYC API does it all in one request. Submit a company name or registration number, and get back verified identity data: legal name, registration status, address, executives, and more.
Companies using automated KYC reduce verification time by up to 95% and compliance costs by 70–85%. CompanyData's KYC API covers 365M+ companies across 200+ countries - from SMEs to multinationals.
