A page size specifies how many records a paged result returns on each page. In server-side paging, the client supplies or accepts this value while the API uses it to return only the requested subset. The server can also provide a default, override the value, or restrict it to control response size and performance. section 5.4.1
Rejecting an oversized request
A request such as /BoardGames?pageSize=200 can return HTTP 400 Bad Request when the endpoint allows page sizes only from 1 through 100. Limiting the value prevents potentially expensive data-retrieval requests and helps avoid response delays and performance drops. section 6.1.2
