BPS REST API - PublicApiReport -> How much data can be returned in one call

1

I am fetching report data from the following endpoint:
https://developer.webcon.com/2023/resources/rest_api5.0/#tag/PublicApiReport/paths/~1api~1data~1v5.0~1db~1{dbId}~1applications~1{appid}~1reports~1{reportid}/get

There are properties for page and size, but information on defaults and max is missing. This seems to be explicitly documented on other endpoints, so i am questioning myself if there are limits at this endpoint or not?
From testing it seems that default for page is 1 and for size is 20.

I would really like to get all available data at the endpoint in one call. So currently i am calling the endpoint once with size=1 specified and check if ViewContent data is returned. If valid data is received then the property "count" is updated with how much data is to fetch. Then i do a second call specifying size=count to retrieve all data. This can work if there is no restriction on how much data can be retrieved in one call.
