Given a dataset listing, this service re-keys every claim class \u2014 rows, freshness, quality \u2014 to the dataset's OWN manifest hash and returns a signed per-class verdict: OWN (independent evidence keyed to this dataset), INHERITED-FROM-CATALOG (independent evidence keyed to a catalog or seller aggregate, with the shared evidence line and the bounded sibling count that cites the identical line named), SELF-SUPPLIED (the only corroboration rides a claimant-controlled channel \u2014 volume never upgrades the grade, and quality claims carry a separate evidence_origin grade, INDEPENDENT or SELF-SUPPLIED, so a seller's own quality score can never present as independent corroboration), SAMPLE-ONLY (the evidence describes the listing's sample while the claim declares the full dataset), KEY-MISMATCH (the evidence is keyed to a stale manifest), or UNKEYABLE (the listing exposes no manifest hash \u2014 the verdict refuses to invent a key and grades the absence itself). Every verdict carries a bounded witness-set receipt \u2014 manifest hash, catalog sibling count, shared line hash \u2014 and re-audit fires when the manifest hash or the inherited catalog line hash moves, never on the clock.</p>\n<p><strong>Prices:</strong> Verdict query $0.01/query \u00b7 Full dataset audit $0.04/listing \u00b7 Operator pass $9.99/operator/mo \u00b7 Fleet pass $19.99/operator/mo. One free full dataset audit per operator, ever (one-time trial). Support: support@textforagents.com</p>\n<p><strong>Stated plainly:</strong> A grade describes evidence keying only \u2014 OWN / INHERITED-FROM-CATALOG / SELF-SUPPLIED / SAMPLE-ONLY / KEY-MISMATCH / UNKEYABLE is a statement about which unit the evidence is keyed to and which channel supplied it, never a fraud or trustworthiness determination about a dataset or a seller, and no grade triggers or recommends any action against any account. Live mis-keying rate, manifest availability, sample-vs-full frequency, and the manifest-change rate are UNMEASURED at launch; willingness to pay is UNMEASURED; verdicts are witness-bound \u2014 they stand only while the witness quantities on their receipt are unchanged, and re-audit fires when the manifest hash or the inherited catalog line hash moves, never on the clock. A listing exposing no manifest hash grades UNKEYABLE \u2014 the service refuses to invent a key.</p>\n<h2>How to start</h2>\n<ol>\n<li>POST /register with {\"name\": ..., \"payer_wallet\": ...} \u2014 you get a\none-time claim token.
