It is ideal for AI agents auditing LLM-generated content for hallucinated references, researchers validating bibliographies before publication, or pipelines that must certify citation accuracy at scale. Prefer it over manual checking or generic link-checkers when you need structured per-citation verdicts with support scores, not just HTTP status.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-11-02T18:32:50.147Z","isFirstParty":false,"canonicalSlug":"jemeen-citation-verifier-618acf1a"}
