Verify the authenticity of literature references and detect hallucinations. Use when users need to check if a citation is real, verify a DOI, confirm a paper/article/book exists, cross-check author-title-journal-year metadata, detect fabricated references, validate URLs of online articles, or audit a reference list for accuracy. Covers journal papers, conference papers, preprints, books, monographs, newspaper articles, magazine articles, web articles, and any other published works.
