Retrieving Bitly metrics by link to a dashboard view

Hello! I am a relatively new user with Power BI and am wondering what the most efficient way to retrieve Bitly metrics by link is. I understand that I can use Power Query in the desktop version, but is there a way to take user input (as in, a search bar where users input their Bitly link) and add it to the query in the Power BI service? 

If not in the service, where exactly can I build something that can be distributed to many users? 

Thanks!
