How this service works
Is this exact sentence on this public page? verbatim / paraphrase / stitched / not_found / unreachable, with an Ed25519-signed receipt logged in a public, witnessed, append-only log.
Output
A JSON object with an outcome field set to one of: verbatim, paraphrase, stitched, not_found, or unreachable. Also includes a receipt object containing the tool name and the log sequence number (position in the public append-only witness log), plus an Ed25519 signature over the result for tamper-evident proof.
Example use cases
AI citation fact-checking
“Check if the quote 'Inflation fell to 3.2% in October' is actually on https://www.reuters.com/article/economy-inflation — I need a signed receipt showing whether it's verbatim, paraphrased, or not found, so I can trust whether the AI's citation is real.”
Legal claim source verification
“Verify whether the sentence 'The company admitted liability in the settlement' appears verbatim or in paraphrase on https://www.courthousenews.com/settlement-details — I need the signed log receipt for my records.”
Misinformation audit
“Someone shared this quote: 'Scientists confirmed the vaccine causes heart failure in 1 in 100 patients' and said it's from https://www.who.int/news — can you check if that sentence is actually there, paraphrased, stitched, or completely made up, with a verifiable receipt?”

Endpoint
POSThttps://neo-collettive.onrender.com/x402/verify-quote?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically attested, auditable answer to whether a specific sentence appears on a public page — not just a scrape or search. It is ideal when the result must be verifiable by a third party (the signed receipt with log position proves what was checked and when). Prefer it over raw web scraping for citation audits, legal evidence, misinformation investigations, or any workflow where tamper-evident provenance matters. The $0.01 USDC per-call pricing via x402 makes it lightweight for per-citation checks in larger pipelines.
Side effects
- URL is not publicly accessible or returns non-200 status — outcome: unreachable
- Quote is fewer than 3 words — request rejected with validation error
- Page requires JavaScript rendering and returns empty content — may return not_found incorrectly
- Network timeout fetching the target URL — outcome: unreachable
- Quote contains special characters that cause matching ambiguity — may affect verbatim vs paraphrase classification
