# Citation Verifier — Existence-Verify a Bibliography Against Public Scholarly APIs The headline existence-verification skill: given a bibliography in any common form, it proves entry-by-entry whether each reference **actually exists** by querying four keyless public scholarly APIs, then maps each result to the canonical AlterLab citation-hallucination taxonomy. It is the deterministic, network-grounded companion to the LLM-driven `integrity_verification_agent` — where that agent uses WebSearch + judgment, this skill uses authoritative API records and a reproducible Python script, so the same input always yields the same verdicts. ## Quick Start ``` Verify the citations in references.bib Check whether these DOIs resolve to the papers I cited Audit my bibliography for fabricated / hallucinated references Does this reference list contain any fake citations or retractions? ``` → Run `scripts/verify_citations.py` over the bibliography, read the JSON, then present a verdict table grouped by severity. Always state the offline/degraded status explicitly if the network was unavailable. --- ## WHAT This Does For each bibliography entry the script: 1. **Parses** the input (auto-detects BibTeX / DOI-list / free-form), extracting title, authors, year, venue, DOI, and arXiv ID. 2. **Resolves identifiers** — looks up the cited DOI/arXiv ID directly when present. 3. **Searches by title** as a fallback across all four sources. 4. **Fuzzy-matches** the cited title (difflib `Sequenc...
