• attestpage_verify_quote

  Checks a quote on its live page: exact, fuzzy or none, offsets and a signed receipt. US$0.01 per call; POST url, quote. Costs US$0.01 per call in USDC via x402 (Base), charged when the call answers below 400 (a no-match or not-found result is charged too); a bad request is refused unpaid. Pay by putting an x402 payment payload in _meta["x402/payment"]. Without one it returns the payment requirements. Docs: https://vehcdj664efetfrsolne5umanq.srv.us/docs/verify-quote

  Parameters:

  • url (required) — string — http(s) URL of the page to check (max 2,048 characters). The whole request body is capped at 64 KB.
  • quote (required) — string — Text to look for on the page, or with match "passages" the claim to find support for (max 1,000 characters after normalisation).
  • match — string — exact; fuzzy (default), which also accepts small differences; or passages, for a paraphrased claim: the 3 passages that share most of its words, scored, as evidence for you to judge (not a verdict).
  • threshold — number — Fuzzy similarity needed, default 0.9.
  • case_sensitive — boolean — Default false; must be false with match "passages".

• attestpage_verify_text_quote

  Checks a quote word for word against text you hold: exact, fuzzy or none, offsets. US$0.005 per call; POST text, quote. Costs US$0.005 per call in USDC via x402 (Base), charged when the call answers below 400 (a no-match or not-found result is charged too); a bad request is refused unpaid.

  Parameters:

  • text (required) — string — The source text you already hold, as sent (max 50,000 characters, and the whole request body is capped at 256 KB of UTF-8, so 50,000 characters of 4-byte text fit; no fetch, no normalising before hashing). Offsets count characters (code points).
  • quote (required) — string — Text to look for in the source, or with match "passages" the claim to find support for (max 1,000 characters after normalisation).
  • end — integer — Optional, with start: the declared end offset, raw code points, exclusive. Give both or neither; not with match "passages".
  • match — string — exact; fuzzy (default), which also accepts small differences; or passages, for a paraphrased claim: the 3 passages of the text that share most of its words, scored, as evidence for you to judge (not a verdict). Not with start and end.
  • start — integer — Optional, with end: the declared start offset of the quote in text, raw code points, 0-based. Only that slice is matched (max 1,000 code points), so the answer is whether the text at these offsets says the quote. Declared offsets are raw; result offsets are into the normalised text. If the slice misses but the quote is elsewhere in the text, result.located gives its position in the whole text. On a slice miss where a number differs, the answer carries match_verdict changed_number and nearest, the closest span on the slice with its diff. nearest offsets count into the slice's normalised text, not the whole text.
  • threshold — number — Fuzzy similarity needed, default 0.9.
  • case_sensitive — boolean — Default false; must be false with match "passages".

US$0.002 per call; POST url. Costs US$0.002 per call in USDC via x402 (Base), charged when the call answers below 400 (a no-match or not-found result is charged too); a bad request is refused unpaid.
