Golden

Golden is a company-data and knowledge-graph platform that builds a continuously updated, citation-backed map of companies, technologies, people, and the relationships between them. The Golden Public API v2 gives developers programmatic, read access to that knowledge graph: retrieve entities and their properties, resolve the schema of entity types and predicates, and run natural-language Queries that return curated, source-cited lists of entities (for example, "companies in the artificial intelligence industry"). Authentication is via an API key passed in the `apikey` header, responses are cursor-paginated, and the API is documented with an OpenAPI 3.1 specification. Golden was founded in San Francisco in 2017 by Jude Gomila, raised roughly $59.5M led by a16z with DCVC, Founders Fund, Gigafund and SV Angel participating, and was acquired by financial- crime-intelligence firm ComplyAdvantage in April 2024; the product site, self-serve plans and the Public API v2 host remain live and reachable.

Golden publishes 3 APIs on the APIs.io network: Entity API API, Query API API, and Schema API API. Tagged areas include Company, Knowledge Graph, Company Data, Data, and Entities.

Golden’s developer surface includes documentation, API reference, getting-started guide, support, pricing, signup flow, authentication, and 19 more developer resources.
