What is RouterBase?

RouterBase is a unified AI API platform that provides access to over 200 frontier AI models from providers like OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, and xAI, including chat, image, video, and audio models. It offers a single OpenAI-compatible endpoint, smart routing, automatic fallback, and unified billing, simplifying integration and management for developers.

How to use RouterBase?

To get started with RouterBase, sign up for an account and generate an API key from the dashboard. Then, point your OpenAI SDK at RouterBase by swapping the base URL. Finally, call any of the 200+ models available. The Playground allows you to try models before integrating.
