Looker Licenses

Hi guys! Could anyone help me understand about Looker licensing?

Today our contract had 170 users "Standard (Creator)" and 20 "Developer (Admin)", I have some questions:

  1. Are licenses classified according to what we set up in "permission sets"? (https://docs.looker.com/admin-options/settings/roles#permissions_and_dependencies);
  2. Assigning a user to a "Developer (admin)" license also counts in the "Standard (Creator)" count or are they separate accounts?;
  3. Wouldn't the viewer license type have extra costs and have an unlimited quantity?;
  4. How does billing for apis calls work?

Thanks!
