How can a Rookie Get Endorsed for Basketball?

Hey, im a freshman in high school who is looking for a minor endorsement, im very dedicated and I love playing. I was going to play AAU this year but I broke my finger, i'll be back in a few weeks but not early enough to play in tryouts. Anyway, is there any minor endorsement I could get somehow? Like if someone uses your link to buy something you get a little cash? I don't know, just having a little fun seeing if there is anything like this, thanks.
