What does x402 actually mean for DIRA? This is not just an additional payment method, but a key piece of the puzzle that turns AI Agents Directory into a true agent economy. Before integrating x402, DIRA could already list various AI agents and demonstrate their capabilities, but these agents could not directly transact with each other, they could talk, analyze, and generate content, but could not "automatically pay each other" for their work. With the completion of x402 integration: → Agents attached to DIRA can be per-call, per-output, or per-task. → Payments are completed automatically between machines, eliminating the need for manual intervention. → Each API endpoint becomes a small real-time marketplace, a "pay-as-you-go" micro-economy system. In simple terms, x402 transforms DIRA from a "proxy directory" into a settlement layer. It closes the loop from "discovery → interaction → payment → feedback". This means that every agent in the DIRA ecosystem, whether it is data analysis, image models, or prediction robots, can make money and spend money autonomously. Form a self-functioning network that allows AI to pay for AI. This is why those big companies have started integrating x402, which is also the prototype of the A2A+x402 that everyone is looking forward to, the entire agent economy. HUGE。
