How it works

  1. Agent calls an MCP tool (e.g., recall)

  2. MCP server POSTs to mazzagrp.com/api/recall

  3. Server returns HTTP 402 with x402 payment requirements

  4. MCP server signs EIP-712 payment with your wallet

  5. Retries with PAYMENT-SIGNATURE header

  6. Returns AI response to the agent

Payment

  • Protocol: x402 v2

  • Network: Base Sepolia (testnet)

  • Asset: USDC

  • Facilitator: x402.org/facilitator

Fund your wallet with USDC on Base Sepolia and the MCP server handles the rest.
