Test REST APIs on a real server (without localhost )

I have a @RestController class in my Spring Boot app. I tested my API's with Postman on localhost and everything seems to be ok.So now I want to test it from another computer.Is there a server/technology which will allow me to test my API's without localhost?So instead of:http://localhost:8095/api/all-users
I have:http://magicServer.com/api/all-users
