How to use ViduS1 API?

Create a session via a POST request with the character's persona, avatar, and voice parameters to acquire a session ID and RTC credentials. 2. Join the AliRTC channel using the token to publish user media and subscribe to the bot's stream. 3. Open a persistent WebSocket connection for control signaling. 4. Wait for the readiness acknowledgement (handling NOT_READY with exponential backoff). 5. Maintain the session with 5-second heartbeats. 6. Send a hangup message to close channels and query final billing information.
