Quick Brief API

Use this when you need a fast cited answer, not deep research: one live web search, relevance-ranked sources, snippet-level digest with 3-6 cited key points in seconds. No API key, no signup — x402 per-call payment only. For full-page depth use the $0.05 Research Brief on the same origin.

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://preview-chat-985505b1-9dc0-470f-9fc3-3704d8b625e3.space-z.ai/api/x402/quick-brief", { method: "POST" });
console.log(await res.json());
