What it does

The USAspending API gives the spending data of the US federal government: budgets per agency, contracts, grants and loans with their recipients and locations, for example to see which companies in a state receive federal contracts. Most searches are POST requests with a JSON filter; answers are JSON. Free, no key needed.
