Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

batch_verify_citations | Runs 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 per item. Requires a signed-in CitationSafe account (Authorization: Bearer <access_token>) — anonymous batch calls are not supported, use verify_citation for anonymous single-text checks. |
get_verificationread-only | Retrieves 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. |
is_this_case_realread-only | Deterministic 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 checks/day per IP, no key required. For unlimited access, pass an API key as "Authorization: Bearer <key>" (contact [email protected] to request one). |
search_phantomsread-only | Searches 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 has no entries yet. |
search_sanctionsread-only | Searches 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. |
verify_briefread-only | Runs 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; sign in at citationsafe.com for full 3-layer verification via verify_citation. Free tier: 5 checks/day per IP (one verify_brief call = one check, regardless of how many citations the text contains); an API key bypasses the daily cap. |
verify_citation | Checks 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's cited for (Layer 3). Returns VERIFIED / UNCONFIRMED / UNCONFIRMED — OUTSIDE COVERAGE / SOURCE UNAVAILABLE per citation, never a bare true/false, with source links. Not legal advice. |
verify_document | Fetches 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. |
