Returning contacts with a specific create date range

I’m trying to get an API call to return the number of contacts created on a specific date/date range.

I’ve currently got this:

Which isn’t working, of course. Is there a page where the query parameters and value formats are listed?
Am I barking up the wrong tree with the contacts endpoint? Any help would be appreciated.

Per the REST Contact Endpoint docs, the date_created field isn’t currently a selectable query parameter.

If you are looking to get a list of the latest ones created, you can do an order=date_created&order_direction=descending to get the the records until we implement additional querying filters.
