> What I did was use the same endpoints that MLB used for their website.

Yes, MLB has/had multiple wide open APIs for grabbing real-time data. You can get 100+ data points for every single pitch, including how fast the ball is spinning as it leaves the pitchers hand.

The major, major, major caveat is that the API includes a notice stating that usage of their API is for non-commercial purposes only, unless you have prior written permission. I’ve spoken with people that have tried to walk the line very closely, and they universally state that MLB lawyers are tenacious (but fair).

I doubt this service has any chance of surviving without some sort of license - if they’re using the MLB APIs.
