What is OpenRouter?
OpenRouter is an API gateway that puts many model providers behind one request format and one billing account. Its catalogue also contains free model routes that cost nothing to call while remaining rate limited.
Key Features
- One OpenAI-compatible API across hundreds of models and providers
- Free model routes alongside paid models, with limits published per model
- Provider routing controls, so you can pin or prefer a specific backend
- Usage and spend visibility in one dashboard
How to Access
Create a key in the OpenRouter dashboard and point your client at the OpenRouter base URL. Free route availability and pricing change, so confirm the current numbers for the model you are calling.
