U.S. Treasury USAspending API

Coverage is U.S. federal spending, with award search endpoints limited to dates from 1 October 2007 and bulk routes extending to 1 October 2000. More than 100 federal agencies submit financial data monthly, but some smaller executive agencies and the legislative and judicial branches are not required to report. Department of Defense and Army Corps contract data have a 90-day source-system submission delay.

Licence note
The Treasury project describes all federal spending data served by the API as "open source and provided to the public as part of the DATA Act." No separate dataset-wide SPDX licence was stated on the checked USAspending data and API pages, so source-system and site documentation still govern interpretation.
Attribution
No attribution requirement recorded.
