Overview
LinkProof citations: verify up to 10 references an agent is about to cite. Accepts DOI, arXiv id, PubMed id, free-text reference, or {title, authors, year}. Checks Crossref/DataCite, arXiv and PubMed; returns per citation exists, matched metadata (title, authors, year, venue, URL), field mismatches, confidence and verdict (verified, mismatch, not_found). Catches hallucinated or misattributed papers.
