Is it possible to retrieve a list of required item specifics by category ?

Detailed Description

You can check NameRecommendation.ValidationRules.MinValues returned in GetCategorySpecifics response to identify required item specifics for a catetory of interest.

If MinValues is 1 or more, it means this Item Specfic is required in listing requests. MinValues is not returned if zero ( 0 ).

Here is the GetCategorySpecifics response for Men's Athletic shoes category (CategoryID: 15709), which shows that US Shoe Size (Men's), Style and Brand are the required item specifics
