Or you could just give your agents a debit card number loaded with only as much money as you specify.
If you're fine with the usual 0.20 - 0.30 USD of processing fees, you definitely can. Cards work well for many things; micropayments are not one of them.
I believe with x402 and USDC you can pay as low as $0.000001 per HTTP request with no fees.
The existing "credit card" infrastructure is not designed to compete with that.
Now some actors like Paypal could have come up with an HTTP 402 standard and implementation 25 years ago but they never did. I am not sure why.
You spin up agents and want them to paid without opening a bank account... or spin-up hundreds of agents... or your country isn't very well integrated with western banking rails. I think there is more to consider.
