AI has already started spending money to buy intelligence on its own, and the infrastructure of Web3 is undergoing a terrible qualitative change. Many people may not have noticed that the top-level analysis tool Nansen's API officially supports the x402 protocol. Previously, when you used Nansen to search for data and check the addresses of major clients, you bought membership and went to check. But now, x402 allows AI agents to purchase the most accurate on chain intelligence directly from Nansen using stablecoins in encrypted wallets on a pay per use basis, without the need for an account or API key. An AI trading agent discovers a fluctuation in the price of a certain coin, and it will instantly pull out a few USDCs to buy Nansen's real-time large account flow data. After confirming that it is the main player entering the market, it will directly complete the order. The entire process may take less than 5 seconds, and AI has completed all the closed loops from discovery to purchasing intelligence confirmation, decision-making, and execution. In the eyes of AI, data is no longer meant for reading, but rather as means of production for trading. When AI has the ability to independently purchase, Web3 is no longer a game of judging who has the fastest hands, but a game of judging whose AI employees are richer and whose intelligence network is denser. If you also want to assign an intelligence officer to your AI, it is recommended that you bookmark research: What is x402 protocol: You can understand it as the bank card protocol of AI. It uses the most original code of the Internet, HTTP 402 Payment Required, so that when AI requests data, it can directly complete the second level payment, saving all the tedious registration and recharge processes. How AI buys data: Now AgentKit from platforms like Fetchai or Coinbase have started integrating this capability. You can write a simple logic that when market volatility exceeds 5%, authorize AI to spend no more than 1 USDC to purchase deep data from Nansen or similar tools. Operation logic: When you or your AI initiates a data request, such as checking the real-time flow of a whale wallet, if this interface is charged, Nansen's server will return a 402 error. The AI will capture this signal and automatically call your authorized wallet to pay fees ranging from a few cents to a few dollars. After the payment is completed, the API will immediately return the complete on chain analysis results. Everyone no longer needs to cling to those free delayed data. The opportunity for future money making logic lies in whether you can build an AI trading loop. Let AI guard the data interface, detect alpha signals, and automatically buy. This kind of data, which is the trend of currency, is the underlying dividend of Web3 in the coming years. Previously, we were participants in Web3, but in the future, we may only be investors and trainers of these AI agents.

Previously, you needed to open an expensive annual membership here to activate, but now they have gradually started to adopt pay as you go billing in order to cooperate with the automatic payment of AI agents.
