What OpenCorporates is

OpenCorporates is a company-data service with web access and an API for working with records on more than 200 million companies across 140 jurisdictions. Its records come from primary public sources and include provenance. The RESTful API returns JSON or XML and requires an API token, supplied in a URL parameter or request header. Teams can instead receive bulk data securely through SFTP, choosing jurisdictions and delivery frequency. OpenRefine users can use its Reconciliation API to match company names with legal entities. Listed applications include entity verification, third-party risk management, investigations, data management and business discovery, across financial and professional services, government, real estate and application development. Essentials costs £2,250/year and allows up to 500 API calls per month and 200 per day; Starter is £6,600/year and Basic is £12,000/year. An Enterprise plan offers bulk delivery and support, with no price listed. The maker also provides free at-scale access for specified public-benefit groups, including investigative journalists, NGOs and universities.
