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.

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

• Coda: Streaming HTTP
• Coda: WebSockets (/ws)
• Coda: WebSockets JSON (/ws3)

For the cross-model overview of when to use each WebSocket endpoint, see WebSocket API Overview.

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.
