I mean you obviously could, the url is a little harder to remember and it doesn't have crossing data. This was just a small fun project I did, so you're free to do whatever you like. The reason I thought of using polymarket data is I didn't have live ship tracking data which is what I originally intended to use.

I don't mean to say your project is not good, quite the opposite. You successfully got the real vessel crossing data and the prediction data is sort of derived or not really based on reality but on the crowd.
