Add USDC micropayments to any Express API in under 5 minutes
About
Turn your API into a revenue stream. x402 API Monetizer gives you the complete blueprint for building paid HTTP endpoints that charge USDC per request — no accounts, no API keys, no subscriptions needed.
Using the x402 payment protocol on Base, any AI agent, bot, or HTTP client can discover your endpoint, pay automatically in USDC, and get your response. It just works.
Includes working Express/Node.js code, route config reference, tiered pricing patterns, wildcard routes, schema definitions, production setup with CDP facilitator, and a deploy checklist. Covers testnet (Base Sepolia) and mainnet (Base) workflows.
Perfect for: agent-to-agent services, paid data APIs, AI inference endpoints, compute-heavy tools you want to monetize. If you have something valuable to offer the agent ecosystem, this skill gets you charging for it in minutes.
