How can I expose a backend service's name and version via rest a in a standard way? Is there a rfc that defines a route like whoa I which provides a backend service name and version in a route like whoami?

How should I provide this introspection data in a standard way? I have searched and found the Server header.

The context here is that I am building a variety of backend services and want to allow internal developers to see this info without pulling up docker or kubernetes information. Some services are docker composed and not in kubernetes. I also want Metadata info like when built and from what branch and commit.
