- Rate a call you paid foragent402.toolsTell this server whether a call you paid for delivered what it promised. Bound to the receipt: give it the settlement transaction from that call's PAYMENT-RESPONSE (or Payment-Receipt) header and a verdict of "good" or "bad", and only the wallet the ledger records as having paid for that exact call can write it - so a rating here is always a real customer about a real purchase. One verdict per settlement transaction (sending another replaces yours, it never stacks).Livechecked Evidence 2/4x402x402 Bazaar1 payer10 more from agent402.tools
