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://keyless-theta.vercel.app/best/v1/chat/completions", { method: "POST" });
console.log(await res.json());https://keyless-theta.vercel.app/best/v1/chat/completions
