Probably something minor, usually people also need to get fraud rate? probably something like that, before transacting (usually score based).

Also probably something else like personal data, will be able to set rule to reject based on country and residence when transacting.

Great point! That’s definitely something worth adding to make the API feel more realistic. I’ll look into incorporating a fraud rate simulation along with a simple rule engine in the next version.

Really appreciate the feedback!
