What OpenCorporates is
OpenCorporates provides access to data on over 200 million companies across 140 jurisdictions. It says the records come from primary public sources and include provenance. Its RESTful API returns JSON or XML and requires an API token, supplied in a URL parameter or request header. Bulk data can be delivered securely through SFTP for chosen jurisdictions and at a preferred frequency. Listed uses include entity verification, third-party risk management, investigations, data management, and business discovery. The OpenCorporates Reconciliation API lets OpenRefine users match company names with legal entities. Listed industries include financial and professional services, government, real estate, and application developers. At-scale data access is free for investigative journalists, NGOs, universities, and anti-crime-and-corruption research groups. Paid API plans begin with Essentials at £2,250/year, which allows up to 500 API calls per month and 200 per day. OpenCorporates holds independently audited ISO/IEC 27001:2022 and ISO/IEC 27701:2025 certifications, and states that it does not hold a SOC 2 attestation.
