**[Tether's Strategic Investment in AIsa to Expand AI Agent Services and Payment Business]** BlockBeats News, October 15 — Tether's independent investment arm, Tether Capital, announced a strategic investment in AI agent services and payment platform AIsa to expand its presence in the AI-driven payments and programmable currency sector. The announcement did not disclose the investment amount. AIsa integrates service access and payments into a single platform, allowing developers to use a unified interface for AI agents to call AI models, data, APIs, software tools, and computing resources. The platform supports usage-based billing in fiat currency or stablecoins, enabling businesses to set spending limits without needing to manage subscriptions or contracts with individual service providers. AIsa stated that over 250,000 agents are currently operating on the platform, which has processed over 100 million transactions. Through a single access key, users can connect to more than 5,000 APIs, skills, and models. Tether CEO Paolo Ardoino commented that as AI agents take on more tasks, users need to retain control over their expenses while authorizing access to services. AIsa is building the necessary infrastructure to support this. [Original Link]
