What is the NEXUS equivalent of list of tags associated with an image - eg http://hub.docker.com/v2/repositories/library/debian/tags/?page_size=20

What would be the equivalent of this command using my own local docker repository
https://hub.docker.com/v2/repositories/library/debian/tags/?page_size=20

Trying to hit my NEXUS repos with a docker repos on 999 for myapp gives me an error
https://my-host:999/v2/repositories/library/myapp/tags/?page_size=20

What would be the nexus equivalenet??

I just want to grab a list of tags for an image
