In this context I think it was fairly clear I was referring to HTTP API. If they want to utilize a sqlite client or query local data in some other way I think that makes sense. You could download the whole project as a project dependency, and build your app as an offline app. I wouldn't expect a Quran app to require internet connection.
I'm glad you picked up on my tone. I'd suggest not writing pointless criticism.
Them: "Hey, we wanted to build an API!" You: "What if you don't build an API, and just download a file? That's the same right?"
