Tools (8)

verify_citationChecks every legal citation in the given text against primary sources: does the cited case exist (Layer 1, CourtListener database lookup — deterministic, no LLM), does a quoted passage appear in the source opinion (Layer 2), and — on paid CitationSafe tiers — does the case support the proposition it
verify_documentFetches a document (PDF, DOCX, or plain text) from a URL and runs the same 3-layer citation verification as verify_citation. Use this when you have a link to a brief rather than pasted text.
get_verificationRetrieves a previously run CitationSafe verification (by the verificationId returned from verify_citation/verify_document, or from a citationsafe.com/v/{id} share link) and returns its full per-citation results.
batch_verify_citationsRuns the same 3-layer citation verification as verify_citation across multiple texts in a single call. Each item is billed against your CitationSafe usage exactly like an individual verify_citation call — batching never bypasses your plan's monthly limit. Max 10 items per batch, 64,000 characters pe
search_sanctionsSearches CitationSafe's database of real court sanctions/orders arising from AI-hallucinated legal citations, by court name, party/case name keyword, or free-text keyword. Read-only, public data — same dataset backing citationsafe.com/sanctions-database.
is_this_case_realDeterministic existence check (Layer 1 only, no LLM) for one legal citation against CourtListener's primary-source database. Answers the single question "is this case real" for one citation — for multi-citation quote-checked verdicts across a whole brief, use verify_brief instead. Free tier: 5 check
verify_briefRuns existence (Layer 1) and quote-match (Layer 2) checks — both deterministic, no LLM — on every citation found in the given text and returns one verdict per citation. The multi-citation counterpart to is_this_case_real. Proposition support (Layer 3) is not included on this free/API-key surface; si
search_phantomsSearches CitationSafe's phantom-citation registry — fabricated case names/citations that have shown up in real, sanctioned AI-hallucination incidents — by case name or the AI system that produced them. Read-only, public data. Returns an empty array (not an error) if nothing matches or the registry h
