Get Started Free →Deterministic anti-hallucination gate for cited references. Resolves each entry in a manuscript .bib file against Crossref, OpenAlex, and arXiv; flags fabricated (identifier resolves to nothing), mismatched (title/author/year disagree), unverifiable (no identifier), unchecked (offline cache miss — never silently OK), and anachronistic (future-dated) citations. Offline-first with a persistent SQLite cache; live network resolution is opt-in. Use when verifying citation existence, auditing a refere

Given the references a manuscript claims to cite, prove (or disprove) that each one exists and matches its cited metadata. This is the verification side of the literature workflow; infrastructure/search/literature is the discovery side.
id → arXiv API; bare title → Crossref title search with a similarity floor.

allow_network=False (default), consult only theSQLite cache and report unchecked on a miss — a skipped check never launders into a clean pass.
"fabricated" is fast and stable.
