When you retrieve data using api, is it better to store this data in another database or is it better to receive data when you need it?

Question

I use the TMDB api to get information, such as movie titles and years of release, but I wonder if I need to create an additional database to store all this information locally, instead of continuing to use the api to get the information? For example, whether to create a movie model and call:

film.title

and thereby access the local database with the header stored in it or call:

Tmdb::Movie.detail(550).title

and thereby make another api call?
