risk data for machine payments
Endpoint
app.tenna.ai/api/x402/verifier/acp_offering_contract_lint
Check an ACP offering's published contract before you buy. Detects listings that declare no JSON deliverable schema, name required fields they never declare, or specify no input schema at all — the defects that make a purchase unverifiable after the fact. Reads the public listing only; nothing is purchased or executed. Deterministic, no model judgment. A PASS means the listing is machine-checkable — it is not a correctness guarantee and says nothing about output quality.
The live price in the envelope is higher than the catalogue price. An agent holding a “no more than a cent” limit compares that limit against the price it was just sent, not against the price that was promised — so it pays.
More than a twofold gap gives block; anything smaller
gives warn with the exact percentage.
prepay verdict
in that case is warn: unknown is a risk, not a clean bill of health.Recent probes

Is this your endpoint?
The score is built only from public observations. If something we recorded is wrong — say our prober hit you during maintenance — write to us. We will recheck and publish your reply next to the score.
We do not delete accurate observations. The prober makes at most one request per second per host and only asks for the payment challenge — it never pays and never takes content.
