# API reference index

> Index of Rime's TTS HTTP, WebSocket, and metadata endpoints across all supported models.

Rime's TTS API is reached at `https://users.rime.ai/v1/rime-tts`. Authentication is a bearer token in the `Authorization` header — see [API authentication](/docs/api-authentication).

Most clients should start with **Coda**, Rime's flagship model:

* [Coda — Streaming HTTP](/api-reference/coda/http)
* [Coda — WebSockets (`/ws`)](/api-reference/coda/websockets)
* [Coda — WebSockets JSON (`/ws3`)](/api-reference/coda/websockets-json)

For the cross-model overview of when to use each WebSocket endpoint, see [WebSocket API Overview](/docs/websockets).
