What is the best way to limit chatroom messages?

Question

So here is the setup:

Creating a Realtime AngularJS chat application. However, I want to limit the messages that the user sees by an API call that defines other messages within their vicinity.

For some reason I can't wrap this around. I researched socket.io, FireBase, PubNub, and I cannot find a suitable way to restrict the data returned by these services based on an API call that sets the parameters.

Thoughts?
