Embedding into site - how many different rooms

Hey everyone! Amazing product here. I understand max people per room is 75 - but aiming for only around 10 per room. So my next question is - how many rooms are available?

For example, is it easy to API into my website 10 different rooms with 10 different people each?

So operationally, could I set up:
url.com/room1
url.com/room2
etc

Thanks!
