iTunes; my card was used on paxful

We're fellow users here, clearly we cannot tell you. I don't think Apple will provide details either. Even if it were possible to trace the details from the card code, and it might not be, then I would think they could only legitimately supply the information to law enforcement if subpoenaed.

Apple won't give you that information, unless perhaps they are able to establish that it was you that redeemed it.

If you bought an iTunes gift card voucher which you cannot redeem then you should first try If you can't redeem your App Store & iTunes Gift Card, Apple Music Gift Card, or content code - Apple Support in case you are either entering the code incorrectly, or the card wasn't activated. For activation issues seek redress from the vendor.

If you have sent the card details to someone else as a form of remote payment, or have bought a card that has already been redeemed, then you have been scammed. See iTunes Gift Card Scams - Official Apple Support for more information.

If you've been scammed there really isn't anything that Apple can do to help you. Read the linked advice. Contact local law enforcement.
