Accept Agent Payments empowers developers to turn any standard HTTP endpoint, AI model, or data service into a paid, agent-consumable resource using Circle Gateway Nanopayments and the x402 HTTP 402 protocol. It provides step-by-step guidance for implementing gasless USDC payment authorization, deploying Express-based payment middleware or proxies for non-Node APIs, safely verifying transactions across supported networks, and preparing metadata for Circle Agent Marketplace listings.
