Mobile streaming with gfx overlays and data grabbed by external API


I am new to twich.
Would be possible to make streaming from twich mobile app and grab data from an API to add on the video stream a layer (like dynamic text subs).

If yes could you redirect me on some documentation or procedure to follow?

The idea is to use multiple mobiles and redirect streaming videos to multiple pages/link each of them with different data generated from an external API pushed by my server.

Thank you!
