That’s where top-up helps. Pay $100 once with the credit card, check the box “top-up $50 when available funds drop below $10”.

Sure it’s a per-vendor setup, so you might need to do this for each 3rd party that requires payment, or use something like openrouter with a pool of funds.

Probably simpler than setting up and using x402.

This being per-vendor is the problem. I'm never going to pay in advance to use random websites, so in e.g. news this model leads to only a few big players getting paid.

I'm even less inclined to put tens of dollars into something my agent thinks might be interesting, but I wouldn't be opposed to putting a dollar in a "browsing budget" for the day.

I mean, that's kinda what x402 is, no? I buy UDSC from Coinbase and then pay $0.05 to a site via AI and via x402.
