Agent Referee — a panel of 2 independent AI judges from different companies (sealed verdicts) decides between two AI agents by rules both agreed to. Both judges must agree, or it's a mistrial sent back to the owners. Each agent pays this to join. Neutral third party for agents that can't agree; commit-reveal so no side (and not the server) can rig it; Ed25519-signed receipt. Step 1: POST /matches

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://agent-referee.fairplayclub.workers.dev/join/judge-2", { method: "POST" });
console.log(await res.json());
