From 2 comments
This could be a great way to charge ai for access to content.
more_corn on HNI've been wanting something like this for a long time. There's a lot of ways this could go wrong, but I hope it works. I'd especially love a video platform using this model. I…

Good to see the micropayments idea implemented
From 1 comment

Card fixed fees make small balances expensive for customers

Questions
Why hasn't this model worked before
From 1 comment
I mean this in the most constructive way possible: why do you think this idea hasn’t worked before, when it’s been fairly obvious and easy to build for a long time? And what’s…

Stripe usage-based billing
From 1 comment
You're right to consider this, as it's an important aspect from a legal perspective. Since Small Transfers doesn't store customers' funds or allow them to withdraw a balance, the…

Lightning Network paywalls
From 1 comment
I think micropayments are important for a healthy web economy. In 2018 I built a pay-per-call API paywall using the Lightning Network (a Bitcoin Layer 2 protocol/network that…
