AirWallet Template: Paid API

This is a minimal Next.js app demonstrating x402 paid endpoints.

Endpoints

• GET /api/health — Free health check
• GET /api/paid/echo?q=hello — Paid echo (returns 402 without payment)

Testing

# Free endpoint
curl http://localhost:3100/api/health

# Paid endpoint (will return 402)
curl http://localhost:3100/api/paid/echo?q=hello

# Bypass for development
curl -H "x-airwallet-bypass: true" \
  http://localhost:3100/api/paid/echo?q=hello

# Run buyer script (pays and fetches)
pnpm buyer
