My bank in France has this service built in. You set the amount and the expiration date and you get a virtual card. It's tied to the first commerce that uses it. That one commerce can use it multiple times as long as there are funds left. It works on Google Cloud Compute I used it last year. Then there is an option to completely block any transaction of my actual card for any online purchases. When I go on a trip I generate a few virtual numbers and write them down in case I need to make an online purchase from abroad.
