The one that comes to mind for me is Privacy.com, though it’s a paid service. If you just want to have a random CC to get past those “we need a credit card to continue” paywalls, I recommend a fake person generator. They usually include a realistically fake CC

It’s worth noting that if you use privacy for free trials, they limit you to 3 cards linked to the same “merchant” (detected by the first transaction that goes through). After 3 cards you have to contact support to reset the limit for that merchant, so the single transaction cards are only good if you never want to shop there again because they immediately burn 1 use out of the limit.
