How it works

1. Agent calls a tool (e.g. agent-card-resolve).
2. MCP server POSTs to https://x402.agentutility.ai/agent-card-resolve.
3. The endpoint responds HTTP 402 with payment instructions.
4. The MCP server signs an EIP-3009 USDC transfer authorization with X402_PRIVATE_KEY and retries.
5. CDP facilitator settles on Base.
6. The endpoint returns the actual response.

The agent never sees the payment flow — it just gets the result.
