Hi,
We are researching networks of fraudulent reviewers on the App Store and needed a dataset for the same. While collecting App reviews, we came across two different Apple APIs: Itunes and Apple App Store.
We had a few doubts regarding them
- Is the Itunes API updated these days as the service was deprecated in 2019?
- From the Itunes API we were not able to collect more than 500 reviews. Is there any similar limit for the App Store API?
- While collecting the app reviews from the App Store API we hit a rate limit. We are working around the rate limit using a sleep time between requests, but can you share the actual rate limit?
- Also, is there any dataset of App reviews that you can share with us for research?
- Are you aware of any other APIs/endpoints that we can use for collection of app reviews?

### Sample Itunes API request for review collection:

curl https://itunes.apple.com/in/rss/customerreviews/page=12clear/id=742044692/sortby=mostrecent/json

### Sample App Store API request for review collection:

curl 'https://amp-api.apps.apple.com/v1/catalog/us/apps/1477966166/reviews?l=en-US&offset=20&platform=web&additionalPlatforms=appletv%2Cipad%2Ciphone%2Cmac' \
