x402 lets AI agents pay for access to protected routes automatically over HTTP 402 — enabling pay-per-use APIs and content for autonomous agents.
Why it matters
x402 lets AI agents pay for access to protected routes automatically over HTTP 402 — enabling pay-per-use APIs and content for autonomous agents.
How to detect
A protected route returns HTTP 402 with machine-readable payment requirements.
How to implement
Add x402 middleware to protected routes with a facilitator URL and wallet address:
import { paymentMiddleware } from '@x402/express';
app.use(paymentMiddleware({
facilitatorUrl: 'https://facilitator.example',
address: '0xYourWallet',
routes: { '/api/premium': { price: '$0.01' } }
}));
Unpaid requests get a 402 with payment instructions agents can fulfil and retry.
How to verify
curl -si https://YOURDOMAIN/api/premium returns 402 with payment requirement headers/body.
