  -H "Content-Type: application/json" \
  -d '{"channel":"base","limit":10}'

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/fc-channel-feed", {

  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "channel": "base",
