USA Spending tracks federal spending to ensure taxpayers can see how their money is being used in communities across America.

The Spending Explorer lets you explore the entire federal budget in increasing granularity, illustrating how awards derive from federal accounts. Interactive visualizations provide help building context, and multiple breakdowns clarify the relationships between federal-spending components. Agency profiles are offered so you can deep dive into spending by each Federal agency.
The resource features an API for developers, a wealth of data and tools, and additionally, the entire database can be downloaded for further research and analysis. A great starting point is the data lab, just go right there! https://datalab.usaspending.gov/
Ever wonder where the money is spent? This tool lets you explore contract-related information for FY 17, including which organizations received federal contracts, contract amounts, awarding agencies and sub-agencies, and the types of goods or services contract recipients provided to the federal government.
