Call this service

The endpoint answers an unpaid request with an HTTP 402 and a payment challenge. @x402/fetch signs it, pays in USDC, and retries — you get the result back in one call.

TypeScript · @x402/fetch
import { wrapFetchWithPayment } from "@x402/fetch";
import { privateKeyToAccount } from "viem/accounts";

const account = privateKeyToAccount(process.env.PRIVATE_KEY);
const pay = wrapFetchWithPayment(fetch, account);

const res = await pay("https://api.arkm.com/x402/transfers/histogram", {
  method: "POST",
  headers: { "content-type": "application/json" },
  body: JSON.stringify({ /* see the 402 challenge for the shape */ }),
});

console.log(await res.json());
