Our mission is to provide rapid dissemination of scientific results at no cost to authors or readers. Providing free Application Programming Interfaces (APIs) helps us to advance that mission by enabling platforms and projects that extend the discoverability of arXiv e-prints and provide valuable services to scientists and interested readers.
We hope this list of APIs, bulk downloads, and tutorials will help you begin exploring the many ways the Library of Congress provides machine-readable access to its digital collections.
CORE provides a central API to access full content from tens of thousands of openly available scientific publications from thousands of OA repositories. Full datasets available by request.
Social media and the web
For data collection from social media, it is typical to use the publicly available APIs made available by the social media platforms, such as the following:
Access data from posts, threads, comments, users and more from reddit and subreddits.
Historical Reddit data has been collected at http://files.pushshift.io/reddit/ as monthly CSV downloads.
Public streams provide access to public data flowing through Twitter. Suitable for following specific users or topics, and data mining. You can also access single-user streams, containing roughly all of the data corresponding with a single user’s view of Twitter.
Access to business data, including location, photos, Yelp rating, price levels, hours of operation, and types of transactions. Also includes a Review API, which returns up to 3 review excerpts for a business.
The Congress.gov API includes bills, amendments, summaries, Congress, members, the Congressional Record, committee reports, nominations, treaties, and House Communications. Over time we will be adding hearing transcripts and Senate Communications. Sign up for a free API key to use.

"Open data" is publicly available data that is structured in a way that enables the data to be fully discoverable and usable by end users. It can be freely used, reused and redistributed by anyone. Its value lies not only in what it does today, but also in what it can do in the future. It is a valuable national resource and a strategic asset to the federal government, its partners, and the public.
