Find US federal court cases by party name, case title, or case number — live search of the PACER Case Locator (PCL) across every federal district, bankruptcy, and appellate court. Returns case number, title, court, filing date, nature of suit, and case type. Requires your own PACER credentials (NextGen); PACER charges your account per search ($0.10/page, capped). Example: pacer_case_search({ case_title: “Lytx v. Sanderson”, _apiKey: “myuser:mypass” }) or pacer_case_search({ party_name: “Nicholas Henderson”, court_id: “ilndc”, _apiKey: “myuser:mypass” })
