The sunset date for the Sunlight Congress API has been extended to September 30, 2017 to accommodate users who need more time to move their applications to the ProPublica Congress API. The Sunlight Congress API will be maintained by ProPublica until the sunset date.
In November of last year, the Sunlight Foundation announced that the organization was planning to shut down Sunlight Labs, and all projects would be moved to GitHub including its Congress API. Shortly afterwards, ProPublica announced that the organization would be taking over five Sunlight Labs projects including Politwoops, CapitolWords, and the Congress API. ProPublica already has its own Congress API, and users of the Sunlight Congress API would need to move to the ProPublica Congress API. The two APIs use many of the same resources, and ProPublica said the company would update its API so that it would have the same functionality as Sunlight’s API.
The ProPublica Congress API provides access to legislative data from the Library of Congress, the Senate, and the House of Representatives. Information that can be retrieved using the API includes congressional activity such as votes, bills, member statements, and nominations.
ProPublica originally planned on shutting down the Sunlight Congress API at the end of August but due to a number of requests, the company has extended the sunset date to September 30.
