The X402 payment standard on the Base chain is driving the mass adoption of AI agent micro-payments — each transaction only costs $0.001 in fees. On the surface, it appears to generate revenue for the platform, but the real value lies behind the transaction data. Every X402 payment reflects the pricing ability distribution of AI services: which agents can generate profits, which tasks are cost-competitive, and the market price anchors for various services. These granular data at the transaction level are redefining the economic models of Web3 applications. From micro-payments to intelligent recognition, the Base ecosystem is validating the feasibility of small, high-frequency transactions in the AI era.
