amex centurion cashout

[notspec]

so i bought this amex centurion fullz, problem is cant check the card with porn site or webcam site as none accept amex.
i found a btc exchange that accepted amex and other cc s without id scans but when i try to do verification i get bad gateway, even tried without socks and antidetect to see if it was faster, still get bad gateway. tried with a generated visa, still get bad gateway.
i tried looking for buying gift cards, no website i found accepst amex.
i dont know if my fullz is dead i cant check it.
what can i do to check an amex card without killing it? drops are out of the question for me i live in big city not outside
