x402 Protocol: How AI Agents Pay for API Calls with USDC
The x402 protocol enables AI agents to make micropayments for API calls using USDC on Base chain. No signup, no API keys — just HTTP 402 responses with payment instructions.
How It Works
Agent calls an API endpoint
Server responds with HTTP 402 + payment details
Agent sends USDC payment on Base chain
Agent retries the call with payment proof
Server delivers the response
