My core idea: The district you are in is a more relatable measure of analysis for federal spending for the average person. You want to know what is going on around you. You can more easily "follow the money" this way.
I have a pipeline that runs nightly/weekly with data digest from USASpending, SAM.gov, and some other big players in the space. You can subscribe to changes and get updates daily/weekly on spending in your district. You can map that to lobbying, new contracts that pop up, as well as what your rep is voting on.
The client libraries are written in ruby and are open source here: https://github.com/govapi-rb
You can also check out the API Docs here: https://thepublictab.com/docs/api
It is deemed "beta" for now.. I'd love any feedback and to hear what is cool and what is not.
Thanks!
