x402 Agent Hub

One call returns an address's native coin, USDC and USDT balances on Base, Ethereum, Arbitrum, Optimism, Polygon, BSC and Avalanche (or a 'chains' subset), plus a total stablecoin USD figure, instead of 21 separate reads. Chains whose RPC fails are listed in chainsFailed. You only pay for successful reads: invalid input, not-found and upstream errors cancel settlement.

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://x402-agent-hub.x402-agent-hub.workers.dev/v1/chain/portfolio", { method: "GET" });
console.log(await res.json());
