How to call Qwen Audio 3.0 models

Qwen Audio 3.0 Realtime Plus holds a live conversation over a WebSocket at wss://api.empiriolabs.ai/v1/realtime?model=qwen-audio-3-0-realtime-plus, not over the HTTP endpoints. Connect with the model id qwen-audio-3-0-realtime-plus and send your EmpirioLabs API key as an Authorization: Bearer header on the handshake. Audio travels both ways as base64 16-bit PCM. A browser cannot set headers on a WebSocket, so open this connection from your server and relay audio to the browser over your own socket. For this family, swap the model value for any supported id: qwen-audio-3-0-realtime-plus qwen-audio-3-0-realtime-flash. Get an API key from the EmpirioLabs dashboard.
