Free Law Project's CourtListener REST API provides case law, PACER and RECAP records, dockets, judges, financial disclosures, oral arguments, citation lookup and graph data, alerts, and legal search. Many endpoints permit experimentation without authentication, but production use should authenticate with a token. Commercial agreements are available for expanded access.
