RouterBase is a unified API platform for accessing 200+ frontier AI models from OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, xAI, and more. It works as a drop-in OpenAI SDK replacement, adding smart routing, automatic fallback, unified billing, usage analytics, BYOK support, and regional processing options for developers shipping LLM-powered products.
RouterBase routes requests to 200+ chat, image, video, and audio AI models through a single OpenAI-compatible API. Developers can swap the OpenAI SDK base URL, use one RouterBase API key, and call models from major providers without managing multiple SDKs or accounts. The platform includes smart routing by price, latency, or availability; automatic fallback when a provider fails; streaming, tool calling, vision inputs, JSON mode, and prompt caching; unified billing; spend tracking by model, key, or project; CSV export and API analytics; configurable per-key rate limits; monthly caps; BYOK for OpenAI, Anthropic, and Google; and optional regional controls for enterprise compliance.
