What it does
This actor searches a quarter-million U.S. federal and state court opinions by case name, party, topic, or court, and returns the citation, cite count, deciding judge, and a link to the full text. Built on CourtListener's case-law corpus, it's tuned for legal research and legal-AI pipelines that need clean, structured precedent rather than scraped HTML. Filter by court, restrict to opinions filed after a date, and bring your own CourtListener token to lift rate limits at scale.
Who it's for
Litigators researching precedent, legal-AI and RAG pipelines needing structured case law, academic and journalistic researchers, and anyone who wants bulk case-law export that Westlaw and Lexis terms forbid.
