# API reference index

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

Send TTS requests to `https://users.rime.ai/v1/rime-tts` and authenticate with 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).

<Warning>
  **Cloud Arcana requests switch to Coda on August 15, 2026 at 12:00 UTC.** New cloud integrations should use Coda or Mist v3. The Arcana references below remain available for migrations before the cutoff. See the [Arcana migration guide](/docs/arcana-sunset).
</Warning>
