If we look at the update of AgentPay v0.2.1 in the overall work of @ worldlibertyfi, it's actually quite interesting. In fact, what they have been working on is a complete "settlement system that AI can use". In the past, AI agents were capable of performing tasks but not spending money. It can tune APIs and run tasks, but the prerequisite is that all resources have been prepared for it. In this mode, AI is more like an automated tool rather than a role that can truly participate in the economy. The upgrade of AgentPay allows AI to pay on its own. The process is also very simple: AI wants to take data → requests → the other party says they want to charge (402) → AgentPay checks if it exceeds the budget → local signature → direct payment → receives the result. It may seem like an additional payment step, but in reality, it's a qualitative change. Because from this moment on, AI has already started making decisions and needs to consider whether the data is valuable, whether to spend money on it, and how much is appropriate to buy. Once AI starts to be able to spend money autonomously, APIs are no longer pre configured resources, but can be purchased as needed. Data is no longer fixed access, but can be traded in real-time. Since we have started trading, what settlement method should we use? USD1 is the meaning of existence. If we use old logic to look at stablecoins, most of them are based on scale TVL 、 profit. But the most important thing is actually the scene, or who is used to 'settle'. In the current high-frequency and automated environment, the biggest fear is volatility. If an asset with a constantly changing price is used, AI's decisions will be disrupted by the price every time, and the cost calculation will be unclear. Eventually, it will converge to stablecoins. And what @ worldlibertyfi is doing is constantly stuffing USD1 into real-life usage scenarios. Previously it was a prediction market, now it's an agent payment, essentially doing the same thing: making USD1 the default unit for settlement. That's also why I find this narrative quite interesting. Most stablecoins are still competing for scale, but USD1 is more like competing for usage rights. Once an asset begins to be extensively used for pricing, settlement, and payment. In fact, what changes is everyone's habits, and over time the entire system will be built around it, which is difficult to replace.
