# Nito API

> One key, every leading model, incognito.

The Nito API is an HTTP gateway at `https://app.trynito.ai`, compatible with the OpenAI and Anthropic SDKs. One organization key reaches the whole [catalog](/models), and the model ID you send picks the model and its privacy level. If you already use either SDK, the integration is a base URL and a key.

For Nito as a product, read [What's Nito](/get-started/what-nito-is).
