risk data for machine payments
Endpoint
x402-store.dgdb.workers.dev/v1/listing-doctor
Why is my x402 service not listed — or listed but never paid? Send your endpoint URL; we fetch your 402 envelope, run the exact SDK validation the CDP facilitator runs, check catalog presence, and return per-check pass/fail with concrete fix hints. Includes two undocumented traps we verified against the live facilitator: a buyer must echo your bazaar extension into the settle payload, and a description over 500 characters makes the facilitator reject every payment. Deterministic, no LLM.
Score
The score is built from observations we collect ourselves: how the endpoint responds, what the envelope contains, how stable the price and the recipient are, who pays and how often. It is deterministic — the same input always produces the same result.
We do not publish the exact methodology yet. If you own this endpoint, write to us and we will show you, item by item, what drags the score down.

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.
