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://api.sitecheck-api.workers.dev/api/btc/fees", { method: "GET" });
console.log(await res.json());https://api.sitecheck-api.workers.dev/api/btc/fees
