Api Endpoint

AttestPage

Use when an agent is about to quote or cite a web page as the source of a claim: send the URL and the quote word for word, and get back exact, fuzzy or none, with offsets and a signed receipt, so a misquote is caught before a user sees it. US$0.01 per call; fact check of citations. For 3 or more quotes on one page, verify/quotes costs less. PDFs are read too, on the full service, with pdf_page and pdf_page_end. 5 free calls a day.
