Questions about the 8x8 Meet service

I have some questions about the 8x8 Meet conferencing service. I didn’t find the answers in the support site and I tried to contact their support several times but with no success.

  1. Can I embed the meeting in my app (using JitsiMeetApi or simple iframe) ?
  2. If I embed the meeting in my app, is there any ad in the end (like in ?
  3. How many simultaneous meetings can I have ?
  4. Should I pay for every participant ? (If I have a meeting with 100 participants should I pay 100 * 9$ ?)
  5. is the Lobby feature available ? (is 8x8 Meet version the same as ?)
