With manuscript text, unresolved \\cite keys and uncited entries are reported. All verdicts are computed in code with zero model calls; checkSupport adds one fast-tier call judging whether each cited abstract supports its citing sentence, both quotes verified. Limited to indexed works: books, theses, standards and web pages are often NOT_FOUND or UNRESOLVABLE, and a clean result is not an endorsement of the cited claim.\n\nPrice: 1.50 USDC on Base (x402).","x-x402-price-usdc":"1.50","x-x402-amount":"1500000","x-audience":"research","x-sample-url":"https://agents.writerslogic.com/api/v1/samples/reference-verifier","security":[{"x402":[]},{"apiKey":[]}],"requestBody":{"required":true,"content":{"application/json":{"schema":{"type":"object","additionalProperties":false,"properties":{"bibtex":{"type":"string","minLength":10,"maxLength":400000,"description":"BibTeX/BibLaTeX text (the contents of a .bib file)."},"latex":{"type":"string","minLength":10,"maxLength":400000,"description":"LaTeX source with a thebibliography environment (\\bibitem) or embedded filecontents .bib; \\cite commands supply citation contexts and are checked against the entries."},"references":{"type":"string","minLength":10,"maxLength":200000,"description":"Plain-text reference list (numbered, blank-line separated, or one per line; APA, IEEE, Vancouver, Chicago)."},"arxivId":{"type":"string","minLength":4,"maxLength":80,"description":"arXiv id or URL; references are read from the ar5iv HTML (.ltx_bibitem), falling back to the PDF."},"pdfUrl":{"type":"string","minLength":8,"maxLength":2000,"description":"Public PDF URL.
