Need help finding user info

I should have been more specific. I need to be able to have the user put in a number into that custom field. Then a GET request is made and the users profile is populated with some meta info that that number represents. So if I setup custom user fields that are blank, I just needed to figure out how to show only the specific custom fields I chose. In other words, don’t show the number the user populated, show the result of the GET request.
