I want to implement iTunes Search API in my app for my users to search for contents on iTunes
https://affiliate.itunes.apple.com/resources/documentation/itunes-store-web-service-search-api/
My app has about 100,000 users. I understand that there's a Rate Limit of about 20 calls per minute. But is the Rate Limit per device, or per app?
If the Rate Limit is per device, then it should be ok. Any one of my users shouldn't be searching for more than 20 times per minute. But if the Rate Limit is per app, then all of my users' searches add up will largely exceed the Rate Limit, then I should look into Enterprise Partner Feed and build a server for my users' searches?
Any help is highly appreciated. Thanks.
