If a REST api is available so it is definitely the best option. Creo already supports REST api and you can display in real-time the result of the queries. Take a look at the Spotify tutorial for more information about REST api: https://docs.creolabs.com/tutorials/spotify.html
Starting from 1.0 we'll regularly update Creo. Version 1.0.1 will be out within a couple of days, followed by another release within two weeks.
