x402.payperbyte.io · x402.payperbyte.io

Verify-before-act risk oracle: POST an action context (message, payload, proposal, payee, tool-call) and get a signed ALLOW/WARN/BLOCK/ABSTAIN verdict + 0-100 safe-to-proceed score + reasons from a LOCAL model (no data egress). The verdict carries an embedded EIP-712 PayloadAttestation — recompute keccak256(answer) and recover the signer before acting. Advisory: the receipt proves provenance/integrity, not correctness.
