these seem extreme for most apis but are likely very good at preventing double charging. a “normal” api call usually costs nothing. i bet stripe and adyen have apis with an average cost per call (to someone) being like $20-$30

the cost to undo a charge is high in people and reputation

How could their API possibly cost $20-$30 per call? How could that even be a business model? Clearly, I am missing something here.

I suspect the OP meant to say charge instead of cost.

ah that makes sense.

unrelated but fun fact: AWS CloudHSM v1 (deprecated now) had a $5,000 api call. that was the cost to create a cluster.

Don’t some bank system transfer like the U.K. cost like ~£25 per transaction?
