Using OpenGovernment data in your app
- You may use our data as long as your use complies with our licensing terms →
- You may find that the data you're looking for is available upstream from us. Familiarize yourself with what's available via our Data Sources.
- No API key is needed at this time; in the future we may require an OpenCongress API key.
- This API is still in flux. We encourage you to sign up to the OpenGovernment developer list so we keep you informed about any changes to it.
We provide data for the following data models:
- Basics of the legislature and sessions
- All People
- Data for a single person, including votes, pageviews, and news coverage
- Committees and committee memberships
- Index of top bills (by most viewed, most in the news, etc.)
- Individual bills, with views and news coverage
- Individual votes, with roll calls
Most pages on the site are available via JSON and JSONP by simply adding .json to the URL and optionally providing a
callback parameter. Most parameters available via normal browsing of the site are also available via the API. So if you request
http://ca.opengovernment.org/sessions/20112012/bills?sort=views, for example, you will see a list of top bills by number of views.
