📝 [SDK] Efficient implementation of text chat without official widget

Hi Vapi team,
I am implementing text chat using directly the API (without the official widget). Currently:

I start a session with vapi.start().
I mute the user's microphone with vapi.setMuted(true)
However, the agent keeps sending audio (we can't unmute it).

My doubts is:

Is there a more efficient method to start text-only sessions that does not consume voice resources (WebRTC, microphone, etc.)?
Is there a way to completely mute the agent audio for a purely text-only experience?
How are credits/resources accounted for when using the API in text vs. voice mode?

I am looking to implement an efficient chat experience without unnecessary audio resource consumption.

Thank you!
