yeah. Its because java bytecode is executed in JVM that's why jvm has better context of the runtime information. correct me If I'm wrong.

Using singleton pattern at a request level basis
But what would happen to it when another request comes that fetches record for another "id". Won't it just return the response for a previous request if it was saved.

Using singleton pattern at a request level basis
Is there a way that the class that contains the function that I am calling to fetch the response handles this rather than handling it across the codebase.

Using singleton pattern at a request level basis
That would require me to pass the same response across my codebase to various functions.

Using singleton pattern at a request level basis
In the api flow if there is some condition met then I am making an api call to another service to fetch response. Now in the same flow later if some other condition is met then I have to make that call again and fetch essentially the same response that I got the first time. What I want is a way to save this response the first time in some variable and in the second call if this is not null then I return this else make the api call again. Is this clear enough or do you need me to provide some code example for this?
