One API gateway for multiple AI providers
OmniRouters provides access to supported models through a single account and API key. Use the model catalog as the source of truth for current availability, pricing, and compatible endpoints.
Choose a compatible API format
- OpenAI-compatible chat:
POST /v1/chat/completions - Anthropic-compatible messages:
POST /v1/messages, for compatible models - Gemini-compatible generate content:
/v1beta/models/{model}:generateContent, for compatible models
API format compatibility does not mean every model supports every endpoint or request parameter. Match the endpoint and capabilities shown for the model you plan to use.
New accounts start without a default free balance. The minimum top-up is $10.
Usage is charged according to the selected model's current pricing.
