OK so let's suppose that there is this API hosted that serves JSON data that is periodically updated and I am building an API that needs to leverage the JSON data that that API hosts, would it be reasonable to make GET requests to the hosted API to fetch that data, and then perform analysis using certain classes and functions in my API, and then serve the resulting JSON as an endpoint in my API?
