Use SiriKit to Return Results from API

I want to use SiriKit for an App I have that will return information from an API I made about a given user. For instance, someone would use the app to find out what they chose as their favorite movie. They would say, "Hey Siri, what is my favorite movie?" and Siri would call the API and respond with, "Your favorite movie is Star Wars".


I looked through the domains that SiriKit provides (https://developer.apple.com/documentation/sirikit#//apple_ref/doc/uid/TP40016875-CH9-SW2) , and none of them looked like they supported this kind of thing. Does anyone know if this is possible?
