Wu Blockchain has learned that Tether's independent investment arm, Tether Capital, has announced a strategic investment in the AI agent payment and infrastructure platform AIsa. As AI agents shift from passive Q&A to actively invoking tools and executing across workflows, traditional human-centric procurement and standalone subscription systems have created friction. AIsa integrates access permissions and settlement layers through a unified interface, allowing developers to connect agents to over 5,000 AI models, data sources, and computing resources via a single API key. It also enables enterprises to set pay-per-call limits and pay on demand using fiat or stablecoins. According to the official statement, the AIsa platform currently has over 250,000 AI agents running, processing more than 100 million transactions to date. https://www.(wublock123.com)/news/tether-capital-invests-in-aisa-ai-agent-payments-70142
