Historical data is available in a number of places and is free to use for whatever purpose, commercial or otherwise.
More recent data is not. Major League Baseball has wide open APIs that give you a huge amount of nearly real-time data, and runs a site where you can bulk download data. For personal, non-commercial purposes only. They will go after you for running a commercial service and demand licensing fees.
That's basically why everything polished is now behind a subscription, while you can DIY all you want.
