Overview

Use before giving an answer that cites web pages: send up to 10 quote and URL pairs, and get back for each an exact, fuzzy or none match, offsets and page status, under one signed receipt: a fact check of each citation against its source. Match "passages" gives each paraphrased claim evidence passages, not a verdict. A PDF is read too, on the full service, with pdf_page and pdf_page_end. A DOI gets Crossref data and a retracted flag. For 1 to 9 pairs, one verify/quote call per pair costs less.
