Our verdict on OpenCorporates
OpenCorporates is a searchable database and data-access service for legal-entity information collected from official sources across more than 140 jurisdictions. It is designed for entity verification, due diligence, investigations, data management, business discovery, government, journalism, academia and application development. Users can search companies and officers, review filings and company events, examine corporate relationships, and follow provenance links to source registries. Access is available through the web and API, with enterprise and bulk-delivery options for larger data requirements.
Pricing is structured around API access and usage limits. Essentials costs £2,250 per year or £225 per month, with up to 500 API calls per month and 200 per day. Starter costs £6,600 per year or £660 per month, increasing the allowance to 2,500 monthly calls and 500 daily calls. Basic costs £12,000 per year or £1,200 per month, with up to 5,000 monthly calls and 1,000 daily calls. Each self-service plan includes internal and external use. Enterprise adds bulk-data delivery, an enterprise support plan and the ability to choose jurisdictions.
The standout strength is structural depth: advanced filters cover jurisdiction, status, type, industry classification, address and trademarks, while records can include filings, officers, ultimate beneficial owners and corporate networks. REST responses are available in JSON or XML, and search results can be downloaded as CSV. That focus makes OpenCorporates a strong fit for research and verification workflows that depend on registry-linked corporate data. It is less suitable for teams seeking contact information, buying intent or technographic coverage, or for buyers whose requirements do not justify the starting price.
