The Problems of Over Fetching and Under Failing

The problems that we faced was, you know, suppose I'm building in a web page. And I have data coming from different resources. So for example, I say for the US state, I want to see a list of jurisdictions and all. But when I hit that endpoint, I basically get details like the name of the jurisdiction,. The code for it and some other related information - which is not needed on this site. This is the second problem of over fetching and under fetching. You basically don't scrap your API that you already developed. You basically create a new version of it, right? The concept of API version. Right.
