# See the payment challenge (nothing is charged)
curl -i -X POST "https://api.ibancheck.co.uk/api/hash-timestamp" \
  -H "content-type: application/json" \
  -d '{"payload":{"hello":"world"}}'

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { ExactEvmScheme } from "@x402/evm/exact/client";

const pay = wrapFetchWithPayment(fetch, client);

// Not sure it's safe to pay? Preflight it first for $0.005:
