How x402 Payments Work
1. Call the tool
Your agent calls a premium tool endpoint via MCP. No API key needed for free tools.
2. Receive payment request
The server returns HTTP 402 with a USDC payment request on Base mainnet.
3. Pay & get data
Your agent pays via the x402 protocol. The server fulfills the request instantly.
