I'm working on a listing app and want to use the Getitemaspectsforcategory API call. This would obviously be used for every listing that gets created. I noticed that the call limit for commerce APIs was 5000 per day. I'm a bit worried that if I end up scaling the app to multiple users, we could easily exceed that limit.
Before I develop a lot of code on this, I'd like to know how the limits are applied (is it per user account or per developer account). And, if by developer account, how would you work around this. Clearly item specifics are required for any listing application and should be able to get those calls from ebay.
Thoughts on this?
