risk data for machine payments
Endpoint
ozmium.org/v1/prop/execute
Run a prop-desk action as the wallet that paid for this call. The x402 fee is NOT the authorisation on its own: you must ALSO transfer OZ on-chain to PROP_OZ_RECIPIENT and pass that hash as `payTxHash` (humans use the burn rail and pass `burnTxHash` instead). Both rails verify a real ERC-20 Transfer from the member, so neither can be forged by sending a field. Requires `actionId` from the desk action list (e.g. trade.open) plus the parameters that action needs. The payer IS the member — you cannot execute on behalf of another wallet, because the identity comes from the settlement rather than from a field you send. Same allowlist, cooldowns and eligibility gate as the human desk.
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We do not publish the exact methodology yet.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.
