How it works

No API keys. Pay as you go.

The x402 protocol handles authentication and billing in a single HTTP round-trip.

Call the endpoint

Send a normal HTTP request — no Authorization header required.

Receive a 402

The server responds with payment details: amount, asset, and destination.

Sign & attach payment

Your x402-compatible client signs a USDC transfer and adds the X-PAYMENT header.

Get the response

The CDP facilitator settles on-chain and you receive the API result — in one retry.

  https://agents.aiscale.pro/api/v1/sentiment/AAPL

// npm install @coinbase/x402-fetch
import { wrapFetchWithPayment } from '@coinbase/x402-fetch';

const fetch402 = wrapFetchWithPayment(fetch, {
  privateKey: process.env.PRIVATE_KEY,
  network: 'base-mainnet',
});

const res = await fetch402(

const data = await res.json();
console.log(data.score); // e.g. 0.72 (bullish)
