You can't do anything regarding getting the API data realtime. That's how they've implemented it. If they support real time then it should be mentioned in their API. What you can do is, periodically call their API from your code behind and see whether there are any updates available. You can use SignalR to push the updates to client side. Implement server side and client side in your application so whenever an update available from your periodical checking, it will push the updates to client side.
