Film id
I have gotten a film id from an api call,
i'm just having trouble finding the correct api call to search the entire movie catalogue from the id alone
(I would like to use this for a search bar component as well, if you could help me find the correct method for this I would be extremely grateful.

I don't know if I understand correctly what you want, but...
The list of all valid IDs can be found here.
