Apt hosted repo, how to expose public key

So im wondering if its possible to expose the public key for an apt repo so that i can automate the adding of repos on clients?
Currently ive done some tests manually for the repo i setup, and it all works, but i dont want to manually add the key on all clients, nor do i want to have the key in my servermanagement software if i can help it. Ideally i want nexus to expose it so i can just curl it from there and use it on the clients.

Is it possible/supported?
Is there a better way?

Hope to get some input on this, thanks!

You could probably create a hosted raw repository and store the public key there in an accessible way.

Sorry for the late reply, i will look into this, thanks!
