Api Endpoint

CitePulse

Bibliography verification for AI research agents — POST up to 20 citations (DOIs or free-text references) and get a per-reference verdict: exists/not-found, retracted/withdrawn (Crossref + Retraction Watch + OpenAlex), and title/author/year mismatches against a real record. Built for agents auditing LLM-generated bibliographies before a citation ships.
