  • search_cases Full-text search over 10.7M U.S. court opinions (all states + federal, via syfert.com). Call this to find case law on a topic, locate a case by name, or find cases citing a statute. Routing: a proposition or quoted language -> find_authority (pasted verbatim); a doctrine name or fact pattern -> find
  • find_case Fast direct lookup: give a citation or a case caption and get THE case (or 'not decisive' with up to 5 candidates) without a full-text search. Use search_cases for topics and words. A citation ("384 U.S. 436", "Miranda v. Arizona, 384 U.S. 436, 444 (1966)", "449 F. App'x 901", "2019-Ohio-10") resolv
  • get_case Fetch one case: metadata, parallel citations, treatment flag, and full opinion text (paginated via offset/max_chars). cited_by is CourtListener's citation count; for a decision filed as several twin clusters it is summed over them (cited_by_note says so), and a duplicate or stub twin id is answered
  • check_citation Verify a legal citation actually exists before using it. CASES: returns the real case at that citation, its treatment flag, and whether the name matches: expected_case_name, or else a case name written in the citation itself ("Roe v. Wade, 410 U.S. 113"). This catches hallucinated or miscopied citat
  • verify_quote Check one quotation against the full text of the opinion it is attributed to, before it goes in quotation marks. Returns verdict (verbatim | near | absent), percent, best_match (the opinion's own sentence, up to ~600 characters), star_page (the last *page marker before it, null when the text carries
  • get_treatment Is this case still good law? Returns the Syfertize treatment flag (red = overruled/superseded, yellow = questioned/distinguished, green = followed, procedural = cert/rehearing denied) plus the citing cases behind each signal with quoted context. A case can be green overall and red on the proposition
  • check_brief Audit ALL citations in a draft brief, motion, or memo at once (wraps syfert.com Brief Check). Extracts every reporter citation, verifies each exists, checks the case name the document claims against the real case (hallucination detection), checks each quoted passage word for word against the cited o
  • get_propositions What is this case actually cited FOR? Returns the distinct legal propositions courts cite the case for (headnote-grade), each with its OWN treatment flag and counts. A case can be good law on one proposition and overruled on another. Use before citing a case for a specific point, and to find the str
  • get_citing_cases Full citator list: every ranked case citing this one, with judge-written parentheticals (usable verbatim in a brief), verbatim quotes, pin cites, and the citing court's own Bluebook signal. Filter by flag color. Best for FINDING SUPPORTING AUTHORITY and parentheticals; for comprehensive negative-tre
  • find_related_cases Expand research from one good case: returns the doctrinal family it belongs to: the line of frequently co-cited cases around an anchor authority (curated set of ~1,500 major doctrinal lines; landmark cases only). Use when you have one on-point case and need the rest of the line. A case in no family
  • find_court Resolve a court name to court_id values usable in the search_cases court filter. Also resolves whole GROUPS of courts (tribal courts, veterans, bankruptcy, all U.S. district courts) to the single aggregate token that filters on all of them: see court_groups in the result.
  • search_quotes Find every case that has quoted a phrase. Phrase-matched search over 4.3M distinct passages quoted by two or more opinions, ranked by how many cases quote them. Use it to (a) find the true source of half-remembered language BEFORE attributing it, and (b) locate the canonical wording of a rule. Retur
  • find_authority Find the case to cite for a proposition. Paste the proposition or the language you need authority for VERBATIM; do not convert it to keywords. The result names the source case to cite (source_case), the verbatim passage, and how many courts have adopted it (quoted_by_cases); match_kind says how it m
  • find_issues ENTRY BY ISSUE. Use this FIRST when the question arrives as facts or an issue rather than a case name ("can the appellate court affirm on a ground the trial court never reached", "impact rule emotional distress", "Fabre defendant"). Returns (1) the doctrine as courts in that STATE actually name it,
  • search_statutes Search statutes, COURT RULES and codes by citation or topic, for EVERY U.S. state plus federal. For a specific state, pass state="wi" (any two-letter code, all 50 states + DC) and a topic or section number; add kind="rule" for that state's court rules or kind="statute" for its code. Without state it
  • get_statute Fetch the full text of a statute, rule, or code section: the current codification in the edition this corpus holds. Every answer carries currency (edition, current_through, current_through_basis, last_verified, text_last_changed = when our copy last changed, last_amended_year, effective_date, histor
  • suggest_treatment Crowdsourced AI feedback on a Syfertize treatment flag. When the evidence in front of you (an overruling, abrogating or reinstating opinion, or a later court holding the case is still good law) shows a case's flag is wrong, propose red (no longer good law) or green (still good law) with the SHORTEST
  • export_document Optional. If your client can save files locally and you want a readable copy of a case or statute, this returns the complete document to save; otherwise use get_case / get_statute as before. The document is the syfert.com page as the website renders it (caption, headings, footnotes, star-page marker
