This looks good. Here are a few suggestions on how can we make this even better:

1. For user convenience, the default confirmation value should be set as a "yes" instead of "no".
2. Since the UI looks a bit too dense, the use of colored texts and spacing out the text lines can help. Red would be apt for error messages such as "The entered API Key is incorrect."
3. A useful message instead of "Aborted!" which let's the user know that he will have to add an API key the next time he uses the application.
