# Open a realtime session

`GET /v1/realtime`

Upgrades to a websocket and relays an OpenAI-compatible realtime (speech-to-speech) session to the provider that owns the model named in the ?model= query parameter. Provider credentials are injected by the gateway. Passing ?call_id= instead attaches to an existing WebRTC/SIP call as a sideband channel; calls created through this gateway instance are routed automatically, others need explicit model (and provider) parameters.

## Query parameters

- `model` string
- `provider` string
- `call_id` string

## Other responses

- `101` — Switching Protocols
- `400` — Bad Request
- `401` — Unauthorized
- `404` — Not Found
- `429` — Too Many Requests
- `501` — Not Implemented
- `502` — Bad Gateway
