https://webmonetization.org/ lists Coil (flat $5/mo) as the first Web Monetization provider: https://coil.com/

Web Monetization builds upon ILP (Interledger Protocol), which is designed to work with any type of ledger; though it's probably not possible for any traditional ledger to beat the <1¢ transaction fee that only pre-mined coins have been able to achieve.

I really like their approach and I paid for Flattr for quite a while when it started. But something big needs to push them to the critical adoption rate. On a number of very techy blog posts, I got... 0 from WebMonetization. And that's on best case audience (coming from HN and tech Reddit).
