How to cache pages with API data

I have a site that is showing static data from an external server via APIs. Is there a way to cache those pages so I can improve the speed of the page? I don’t tthink WUReducer would work because the data is retrieved from API and not Bubble DB. Would Cloudfare work in this situation?

Maybe this would work for you

The external DB is pretty big, so I am not duplicating the data in my Bubble DB. Otherwise WUReducer can do the Bubble data caching and WU reduction.
