Search US federal court opinions or RECAP dockets by keyword, court, and filing date. Built on the official CourtListener API from the Free Law Project, the same non-profit source that powers most legal-tech case law search.
Built for legal researchers, litigation-support and collections teams, journalists covering court cases, and anyone doing due diligence that needs to check if a person or company has been party to federal litigation.
Input
{"query": "antitrust","resultType": "opinions","court": "scotus","filedAfter": "2020-01-01","maxResults": 20}

|---|---|---|
query | string | Keyword search (case name, party, or legal topic). |
resultType | string | "opinions" (case opinions) or "recap_dockets" (federal case filings). |

Output
{"resultType": "opinion","caseName": "Trump v. Slaughter","court": "Supreme Court of the United States","courtId": "scotus","docketNumber": "25-332","dateFiled": "2026-06-29","citation": [],"citeCount": 0,"judge": "John G.

How it works
Direct calls to CourtListener's official public REST API
(courtlistener.com/api/rest/v4/search/). Works anonymously for casual use;
CourtListener's own rate limits apply, higher volume needs your own free API
token. No proxy, no scraping.
Pricing note
Billed per search, not per result returned — a broad search that returns 200 results costs the same as one that returns 2.
