Feature Request: API to support cached results

[Frooodle]

Right now if you want to sure the API content/dupes to grab data it will take 5+ seconds due to the backend querying plex etc. It would be nice if there way a way to grab this data from the last made query in order to reduce time on the API Or Separately/Additionally Have a cached API to return Total MB size of Default selected duplicates to delete and total count of duplicates. Useful stats for dashboard apps for monitoring etc
