How to call it

# See the payment challenge (nothing is charged)
curl -i -X POST "https://netintel.dev/email-auth" \
  -H "content-type: application/json" \
  -d '{"domain":"example.com"}'
import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { ExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client().register(
  "eip155:8453",
  new ExactEvmScheme(privateKeyToAccount(process.env.AGENT_KEY)),
);
const pay = wrapFetchWithPayment(fetch, client);

// Not sure it's safe to pay? Preflight it first for $0.005:
// GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fnetintel.dev%2Femail-auth
const res = await pay("https://netintel.dev/email-auth", {
  method: "POST",
  headers: { "content-type": "application/json" },
  body: JSON.stringify({"domain":"example.com"}),
});
console.log(await res.json());
