B.AI is model-access and economic infrastructure designed for AI agents, bringing access to globally available leading AI models, payments, and settlement into one service. Its main working surface is a unified API, through which an agent application can call models while keeping service purchasing and financial settlement within the same operating layer.
The product is aimed primarily at developers and teams building autonomous agents, automated applications, or shared model-access services, while also covering people who need direct access to multiple models. Programmatic use depends on integration with the unified API, and economic coordination runs through B.AI’s borderless payment and settlement network; the official product description also identifies anonymous model access as part of the service.
