USAspending.gov is the official open data source of federal spending information operated by the U.S. Department of the Treasury's Bureau of the Fiscal Service, implementing the DATA Act's transparency mandate. The underlying USAspending API (api.usaspending.gov) is a free, public, unauthenticated REST API that exposes federal contracts, grants, loans, direct payments, and other financial assistance awards, along with agency budgets, federal account and Treasury Account Symbol data, recipient profiles, and COVID-19 / disaster emergency relief spending. Most search and listing endpoints accept a POST with a JSON filter object rather than query parameters, given the complexity of the filter combinations; simpler lookup endpoints use GET with path parameters. The API and the usaspending-api server are open source.
