api.relayshield.net

Check whether a phone number appears in criminal marketplace infrastructure or pivots to known scam wallets, kits, or actors via RelayShield's threat-intelligence corpus, and whether its SIM/eSIM was recently swapped (Twilio Lookup v2, cached 24h). Returns a high/medium/unknown verdict with timestamped evidence reasons. Call before your agent trusts an unknown caller or smishing sender.

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://api.relayshield.net/v1/payg/phone-reputation", { method: "POST" });
console.log(await res.json());
