Question:
Calling external APIs through fiware orion context broker to validate using keyrock

Description:
I am a student working on a project and exploring viability of using fiware for that. So far I've learnt that to call external APIs we can use registrations for an entity to fetch dynamic data.
Here is the situation:
In my project, I am calling external APIs for fetching some data at frontend.
I want to add access control for users so that they are restricted from calling the APIs if not permitted. For this reason I am trying to find out a way such that keyrock can validate the requests so that I don't have to manually validate these external APIs. Since these aren't related to any entity I don't want to use registration for this purpose.
I intend to do user management through keyrock itself. Currently keyrock can restrict based on resources (i.e. URL path) of the application and permission. I am very confused at this point that if I add an API call at any page to fetch data from external API, how can I make use of keyrock access control in this situation.
Also, can I make orion call the external API somehow and make the data an entity?
Any help and hint is greatly appreciated. Thanks in Advance.
