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://saylorinnovations.com/api/evm/optimism/allowance/0x4200000000000000000000000000000000000006/0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85/0x4200000000000000000000000000000000000006", { method: "GET" });
