Crunchbase
Crunchbase is a leading source of private and public company, funding, and investor data - firmographics, funding rounds, acquisitions, investors, people, and events across the global startup and business landscape. The Crunchbase Data API (REST v4, base https://api.crunchbase.com/v4/data) exposes this graph programmatically through four surfaces - Entity Lookup, Search, Autocomplete, and Deleted Entities (deltas) - for web intelligence, reference data, market research, sales and investment prospecting, and enrichment use cases. It is a read-only RESTful service authenticated with an API key (user_key query parameter or X-cb-user-key header). Access is subscription-gated: the full API requires a Crunchbase Enterprise or Applications license, with a reduced Basic API available to Crunchbase Basic plan holders.
