The Open State Project API, provided by Sunlight Labs (part of the Sunlight Foundation), is part of the Sunlight Labs community of open source developers and designers dedicated to opening up our government to make it more transparent, accountable and responsible. The Open State Project API is a RESTful API for accessing state legislative information in a JSON format.
Sunlight Labs announced this week that 25 of 50 states are now integrated into its Open States API. This puts machine readable state legislative data covering approximately two thirds of the US population into the hands of developers. In addition to the expanded coverage, the team at Sunlight Labs has also been busy with improvements and new features.
