Exchange REST API Pagination #
HootDex Exchange uses cursor pagination for all REST requests which return arrays.
Cursor pagination allows for fetching results before and after the current page of results and is well suited for realtime data. Endpoints like /trades, /fills, /orders, return the latest items by default. To retrieve more results subsequent requests should specify which direction to paginate based on the data previously returned.
before and after cursors are available via response headers HD-BEFORE and HD-AFTER. Your requests should use these cursor values when making requests for pages after the initial request.
||Request page before (newer) this pagination id|
||Request page after (older) this pagination id|
||1000||Number of results per request. Maximum 1000 (default 1000)|
Before and After cursors #
The before cursor references the first item in a results page and the after cursor references the last item in a set of results.
Before Cursor #
To request a page of records before the current one, use the before query parameter. Your initial request can omit this parameter to get the default first page.
The response contains a HD-BEFORE header which returns the cursor id to use in your next request for the page before the current one. The page before is a newer page and not one that happened before in chronological time.
After Cursor #
The response also contains a HD-AFTER header which returns the cursor id to use in your next request for the page after this one. The page after is an older page and not one that happened after this one in chronological time.
Cursor pagination can be unintuitive at first. before and after cursor arguments should not be confused with before and after in chronological time. Most paginated requests return the latest information (newest) as the first page sorted by newest (in chronological time) first. To get older information you would request pages after the initial page. To get information newer, you would request pages before the first page.
