We've released a bug fix for productprovider API and aligned it with the rest of our APIs which means there is now a limit of 500 providers per request, and the default is 100 providers per request.
A note about our APIs and pagination
Most of our APIs support that returns big collections supports Top and Skip for pagination.
skip - Number of records to skip. Must be greater than or equal to zero.
top - The number of records to retrieve (default 100, max 500).
