One API

One API is an open-source platform designed to unify access to multiple AI model providers through a single, consistent API interface. It acts as a gateway that allows developers to manage and route requests to different large language models and AI services without needing to integrate each provider separately. The system supports multiple backends, enabling users to switch between providers or balance usage based on cost, performance, or availability. It includes features such as authentication, rate limiting, and usage tracking, making it suitable for production environments. One API also provides a web-based dashboard for managing keys, monitoring usage, and configuring routing rules. Its architecture is designed for scalability, allowing teams to deploy it as a centralized layer in their AI infrastructure. By abstracting the complexity of working with multiple APIs, it simplifies development and reduces vendor lock-in.
