pubmed-verifier

Reference checker for AI-fabricated citations: batch-verify PMIDs against PubMed and catch the hallucination existence checks miss — a REAL PMID pointing to a DIFFERENT paper. Five-state citation verification (correct / mismatch / partial / invalid / unknown), citation-context parsing, Crossref DOI cross-check, retraction detection (capped at partial), correct-PMID suggestion, arXiv ID verification, plain-text reference list parsing, formatted reference lists (GB/T 7714 / Vancouver / APA / AMA), OpenAlex DOI fallback for non-Crossref registries, Chinese-reference title search, CSV/JSON claims, HTML/JSON/text reports. Four data sources: NCBI, Europe PMC fallback, Crossref, OpenAlex. Network failures are honestly reported as unverified, never as "not found". Zero dependencies, runs fully local. Triggers: verify PMIDs, check citations, citation audit, reference check, citation check, batch verify references, AI hallucination detection, verify DOI, DOI check, citation formatting, reference formatter, GB/T 7714.
