ID 511555 - API: No documentation on which endpoints only return 100 items, and no documentation on how to increase this default

Problem summary
The Flix API by default sometimes only returns a maximum of 100 items when queried. This is expected but we are missing documentation on how to get more than 100. 
 
Customer reported version
Flix 6.3.7
 
Expected behaviour
API documentation found here should clearly list all API endpoints which only return 100 items, and give examples on how to increase the number of returned items.
 
Actual behaviour
No documentation on which API endpoints only return 100 items. 
No documentation on how to increase this default number.
