I've recently used Axate (www.axate.com) on a news website. You top up credit, and then pay per article.

I don't want to top up, I just want to be charged directly.

Also "Which sites are using Axate?", I don't recognize any of the sites on that list.

I don't think it will ever be feasible to be charged directly, transaction fees are just way too high (and it's only marginally better on the crypto side). A postpaid system would work I suppose, ie you pay your total at the end of the month. But postpaid usually involves a credit check (in north america at least), so prepaid is really the only universal option.
