Flow

Use when an agent is making an irreversible payment and needs one verdict over BOTH sides of the spend. Flow bundled verdict ($0.05): send the contract and the payee (optional expectedPayee catches address-poisoning look-alikes; amountUsd adds size-aware risk). Returns one decision (ALLOW / REVIEW / BLOCK), a combined 0-100 score, the contract's full safety grade, the payee's kind/activity grade,

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://flow-kg4x.vercel.app/api/verdict", { method: "POST" });
console.log(await res.json());
