I have been trying to generate a list of all Roblox accessory ids and noticed that after reaching a certain page API does not return any items. After some testing, I went to the Roblox catalog and attempted to reach that page to check if there are any items. Even though catalog says there are 327 pages with 30 items per page I am unable to reach page 35 or further. In this example, I am only able to access 1049 items out of 9790. I have also tried subcategory “Hair” which has 648 items and I am only able to access around 400 items.
Here is the api URL used to retrieve data: https://search.roblox.com/catalog/json?Category=11&Subcategory=19&IncludeNotForSale&Direction=2&ResultsPerPage=30&PageNumber=34
