Welcome
Government-verified business intelligence on U.S. organizations, legal entities, locations and people.
The BrightQuery API gives you government-verified business intelligence on more than 100 million U.S. organizations, sourced from over 100,000 government agencies including the IRS, Department of Labor, Secretaries of State and USPS. Every record is linked by the BrightQuery identifier, bq_id: resolve a company once, then pull its firmographics, financials, locations, executives and corporate family tree.

- SDKs: client libraries for C#, Python and TypeScript, generated by APIMatic, with code samples on every endpoint.
