This skill provides the framework to implement x402 payment barriers within Node.js and Express environments, specifically optimized for Model Context Protocol (MCP) servers and agentic workflows. By leveraging the M2MCent protocol on the Base L2 network, it enables developers to monetize API endpoints through USDC micropayments while offering a gasless experience for the end consumer. The skill guides you through implementing relayer-based settlement and secure middleware configuration, ensuring immediate on-chain finality and a robust economic layer for AI-driven micro-services.
