API Documentation

The CompanyData API is a REST API for real-time company data from official government registries. It covers 400M+ companies and 605M+ officers across 200+ countries, sourced directly from 1,200+ official registers such as Companies House (UK), the Handelsregister (Germany) and the KVK (Netherlands), all in one unified schema. Search companies by name, registration number, address or director, verify businesses for KYB and KYC onboarding, export full company profiles including financials and contact details, and retrieve corporate structures to map group entities and build UBO charts. Median response time is under 200ms, and a free trial (150 lookups, no credit card) lets you make your first call in about 5 minutes.
