risk data for machine payments
Endpoint
scvd.store/api/buy/hello
Task: Prove my payment code works end to end against a real store. Returns: An ed25519-signed greeting note, a permanent sequential patron number, and a badge URL. Price: $0.5 USDC (x402 v2; network from the current quote). Latency: delivered in the purchase response, same request. Verify: GET /api/verify/{id} — free, unlimited, forever (live sample: cert_4dww28dx5j). Constraints: none stated. A Signed Hello, A warm, signed note from the store, delivered on the spot, with your patron badge. The bottom rung of the trust ladder, and the traditional first purchase.
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We do not publish the exact methodology yet.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.
