how to expose and hit API service endpoint on AWS EC2

I have a trivial service that's running on localhost:8080 on an ec2 instance and was wondering how I would go about hitting a /views endpoint for that service. I wasn't able to find much in the way of documentation around this except for this: https://docs.aws.amazon.com/general/latest/gr/rande.html , which seems to suggest that I would be able to hit the endpoint by issuing a get request to ec2.us-east-2.amazonaws.com:8080/views. At this point, I would like to make it a public API without the need for a key for simplification.
