There's already an API, but the mobile app has additional options for length/style of response that are pretty nice. I'd like seeing similar functionality brought to the API. Full disclaimer, I'm just a tinkerer, not a major app developer, so my desires may be exceedingly niche.
I'm thinking it could be supported without breaking anything existing by just adding additional summary_type options? Unless there's more than are documented currently there's just 'summary' and 'takeaway'. The app has those two styles, plus an ELI5 style, and 5 different length options (though I just noticed that length appears faded for 'key points' in the app, so maybe that only effects 'summary').
