## What is UnoRouter?

UnoRouter gives developers a single API key and a single base URL for chat models from several vendors. Requests use the OpenAI chat completions format, so existing SDKs and tools work after changing the base URL.

The gateway tracks provider health and moves a request to another provider when one is slow or out of capacity. Usage is billed from one balance, and a public pricing page lists the cost per model so teams can compare before they switch.

## Who is UnoRouter for?

Developers and small teams who build apps or agents on top of language models and want to try or combine several models without managing a separate account and key for each vendor.
