X402 Express Monetization Wrapper
Integrates x402 paywalls and machine-to-machine (M2M) monetization into Node.js Express APIs using USDC on Base L2.
The x402-express-wrapper skill enables developers and AI agents to implement automated monetization by wrapping Express.js endpoints with x402 protocol paywalls. It facilitates automatic micro-settlements in USDC on the Base Layer 2 network, allowing services to charge for individual API calls or data access. This skill is particularly useful for building monetized Model Context Protocol (MCP) servers or micro-SaaS platforms where agents pay other agents for processing power, providing a gasless experience for consumers while ensuring immediate settlement for providers.
