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, 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.
