What x402Nova Provides

  • Hosted proxy that only forwards traffic once Coinbase x402 settlement succeeds.
  • Dashboard for registering routes, monitoring buyers, and tracking USDC volume.
  • Optional self-host packages (Firebase Functions + facilitator) if you want full control.
  • Reference Express server that shows the minimal backend changes required.

Your Responsibilities

  1. Sign in to the dashboard and register each payable surface as a route.
  2. Share the generated proxy URL with agents or frontends that should pay per call.
  3. Watch metrics update automatically after each verified payment.
Agent → x402Nova proxy (HTTP 402 with x402 instructions)
Agent pays → retries with X-PAYMENT
x402Nova verifies & settles → forwards call to your API → returns response

Launch Checklist

  1. Publish your first route and confirm the proxy works with the API Tester.
  2. Share this documentation (x402nova.app/docs) with integrators.
  3. Export transactions for reporting if you need deeper analytics.
  4. Contact us for higher rate limits, additional assets, or managed facilitator hosting.
