How It Works

1. Agent calls a tool (e.g. weather_current with { city: "Paris" })
2. MCP server returns the endpoint URL + payment info
3. Agent pays via x402 (USDC on Base or Solana)
4. Agent calls the endpoint with payment proof
5. Real-time data is returned

{
  "endpoint": "https://api.friwol.org/weather/current?city=Paris",
  "price": "$0.002 USDC",
  "payment_protocol": "x402",
  "network": "Base (eip155:8453) + Solana",
  "description": "Current weather conditions in Paris."
}
