CourtListener REST API v3.11 - Libraries

CourtListener is a legal database which has collected nearly 2.5M (and growing) legal opinions with rich meta data and citation network. The Opinions in the site's archives date back to the 1700s, making this a deep, rich source of data for many research projects. The CourtListener API allows users to access the legal data using REST calls. Users can make queries to get opinions, citations, citations by user, cites, jurisdiction, search, and coverage. An account is required with service. Free Law Project provides access to legal materials, legal research tools, support for academic research on legal corpora and more.
