It took a ridiculous amount of effort, but it looks like we're starting to go somewhere with this. The complexity of crypto is, um, complex and very very not user friendly. I had money in my Phantom wallet, but that wouldn't connect. I suspect it's because my USDC was on the wrong network. So then I tried the Base wallet, from Coinbase. I couldn't send money from my Phantom wallet to my Base wallet for whatever reason, so finally I used Apple Pay to load $5 (the minimum) into my Base wallet, so that I could click the button, finally, to give you $0.01.

Except it still didn't work. When I used the mobile browser, I clicked the links and it looks like it wanted to take my money, but it returned to the site after going to base, without actually taking money. So then I used the Base app's browser to visit the site. It more convincingly tried to take money out of my wallet but the site returns Request failed: 402, which is confusing, and doesn't actually take my money.

This sounds like what I saw when i tested it with another free facilitator, that one wasn't publishing the transaction to the network. I suspect that the current one, payai also may have occasional troubles posting the transaction, though I do see 4 cents dropped to the account since poating, so the thing works at least for some) Coinbase facilitator would've been more reliable I thunk, but it requires a registration, kyc and all that jazz which I don't want to bother with)
