Phoenix Zero Safe Check

Boolean pre-flight check for L2 transaction safety across all 12 chains (?chain= param, default: base). Returns safe=true/false with reason code. Revert ratio data available for Base and Arbitrum only (eth_getBlockReceipts); other chains use RTT-only analysis. Optimized for high-frequency agent calls.

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://rtt.phoenix-ai.work/api/v1/safe", { method: "GET" });
console.log(await res.json());
