How it works
- Agent calls an MCP tool (e.g.,
recall) - MCP server POSTs to
mazzagrp.com/api/recall - Server returns HTTP 402 with x402 payment requirements
- MCP server signs EIP-712 payment with your wallet
- Retries with
PAYMENT-SIGNATUREheader - 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.
