Represents the page number if the dataset is paged, this parameter can be used together with page_size, which is default set to 500. Set this parameter to -1 if you don't want paging to be applied.
Represents the size of a page, this means that by setting this parameter, you can alter the amount of results that are returned, in one page (e.g. page=1&page_size=3 will give you results 1,2 and 3).
Instead of page/page_size you can use limit and offset. Limit has the same purpose as page_size, namely putting a cap on the amount of entries returned, the default is 500. Set this parameter to -1 if don't want paging to be applied.
Represents the offset from which results are returned (e.g. ?offset=12&limit=5 will return 5 results starting from 12).
