Right API to Connect My App with Monday Night Football?

Hello!

As an ambitious developer, I am looking for an API to connect my newly developed app with Monday Night Football. Then, I want to use my application to stream NFL matches on different FireStick devices. In actuality, the list of these https://www.firesticktricks.com/watch-nfl-monday-night-football-on-firestick.html NFL streaming apps for Monday Night Football like Sling TV and fuboTV, motivated me to build an app like these.

So, I decided to conduct a mock test on whether I can create an application like these and can connect it with Monday Night Football and stream live broadcasts on Amazon Fire Stick devices. In addition, what is about VPNs? Are these mandatory to run such apps?

Definitely, it sounds like a challenging venture. I need your guidance and help.
