According to CoinMeta, Tether Capital, the independent investment department under Tether, has announced a strategic investment in AI's intelligent agent payment and infrastructure platform Aisa. As AI and agent shift from passive question-answering to actively invoking tools and executing across workflows, friction has arisen in the traditional human-oriented procurement and independent subscription systems. Aisa integrates access rights and the settlement layer through a unified interface, allowing developers to connect intelligent agents to over 5,000 types of AI models, data sources, and computing resources via a single API and key. It also supports enterprises to pay on a per-call basis using fiat or stablecoins, with limits set according to the number of calls (pay-per-call). Officials state that there are currently over 250,000 AI intelligent agents running on the Aisa platform, which has processed over 100 million transactions in total.
