PageRequest

Parameter	Location	Type	Required	Description
`key`	query	[u8]	false	key is a value returned in PageResponse.next_key to begin querying the next page most efficiently. Only one of offset or key should be set.
`offset`	query	[u64]	false	offset is a numeric offset that can be used when key is unavailable. It is less efficient than using key. Only one of offset or key should be set.
`limit`	query	[u64]	false	limit is the total number of results to be returned in the result page. If left empty it will default to a value to be set by each app.
`count_total`	query	bool	false	count_total is set to true to indicate that the result set should include a count of the total number of items available for pagination in UIs. count_total is only respected when offset is used. It is ignored when key is set.
`reverse`	query	bool	false	reverse is set to true if results are to be returned in the descending order.
