Check whether a scholarly work is openly accessible and return the best legal free URL, license, and version (via Unpaywall).
Check whether a scholarly work has been retracted, corrected, or had an expression of concern raised (via Crossref + Retraction Watch).
Resolve a scholarly identifier (DOI incl. shortDOI aliases/PMID/PMCID/ISBN/ISSN/arXiv/ADS/WHO IRIS) to structured CSL JSON metadata.
Resolve scholarly identifiers (DOI including shortDOI aliases, PMID, PMCID, ISBN, arXiv, ISSN, ADS bibcode, WHO IRIS URL) into formatted citations (10,000+ CSL styles) and bibliography exports (BibTeX, RIS, EndNote, CSV…), and check retraction, open-access,…
Audit a whole bibliography (BibTeX, RIS, or CSL-JSON) in one call — per-entry fabrication verdict and retraction status, plus a corpus summary.
Export resolved citations to a reference-manager file format (RIS, BibTeX, CSL JSON, EndNote XML, RefWorks, NBIB, Zotero RDF, CSV, or plain text).
Format one or more scholarly identifiers as citations in a chosen style (Vancouver, AMA, APA, IEEE, CSE, or any CSL style ID).
Verify whether a claimed citation matches the actual paper at its identifier (detects the real-DOI/fake-title fabrication pattern common in LLM hallucinations).
