  title: USAspending Agency Recipient API
  description: The USAspending API provides free, public, unauthenticated access to U.S. federal spending data - contracts, grants, loans, direct payments, and other financial assistance awards, plus agency budgets, federal account (Treasury Account Symbol) data, recipient profiles, and disaster/emergency (including COVID-19) relief spending. USAspending.gov is operated by the Treasury Department's Bureau of the Fiscal Service to implement the DATA Act's federal spending transparency mandate. Most search and listing endpoints accept a POST with a JSON body describing filters, fields, sort, and pagination, because filter combinations are too complex for query strings; simpler single-resource lookups use GET with path parameters. This document is a representative, hand-authored subset of the full API grounded directly in the official API Blueprint contracts published in the usaspending-api GitHub repository - it is not a complete mirror of every endpoint and field.
