Almost done. The frontend and backend are both working now. I've also created a very easy-to-use API for developers.
It's going to be the simplest and fastest way to put virtually any digital content behind a lightning paywall. 
Discussion
I appreciate you working on this but I think the paywall approach is exactly backwards. Mental transaction cost is too high & anything that can be copied at zero marginal cost will not be able to find a market price, as markets lose their usefulness once supply approaches infinity.
But who knows. Maybe I'm wrong.
I read your blog on this topic, and I must say it was very thoughtful, not just the usual 'I hate paywalls' argument, but a well-reasoned, philosophical perspective.
That said, from my side, 'Zap to Decrypt' has much broader applications and can be implemented in ways that wouldn’t conflict with your personal stance. New open API will exponentially expand the scope.
I also believe that not having a paywall option (primary mode of monetization for many), especially on a network like Bitcoin, which can handle it far better than any fiat currency, feels a bit unfair.
I wrote this to just let you know, I have great respect for your work, and my goal is simply to build on your ideas, not oppose them.
I've thought about this also. I don't think digital goods must always go immediately to available for everyone at zero cost. There is a gradient of scarcity even with digital goods. Yes, the next marginal unit is at near zero cost to produce, however that first non-identical unit is not at zero cost and is still scarce. Each person that makes a copy contributes to it becoming less and less scarce until there are hundreds of thousands of copies and it is so available that it's no longer an economic good. Skipping over that transition period, I think misses out on a market opportunity and for value comparisons to be made that can help guide the direction of digital goods and what customers value the most.
Yes I don't want to think, I want the algorithm to do it for me.
Why would I use frictionless money to reward a creator, when I can use centralised fiat systems to enslave them.
Please take my data, use it manipulate me, rob me of my time and make me think that getting free shit is freedom!
Would love to use this instead of Spotify premium

We find this useful, and installed ZapIt on LibrarianDetective.com. I'll update it with this new version.
this idea has been tried 15 times in the past 6 years
Trust me, no one knows this better than I do. I built one a year and a half ago, and the biggest problem we always faced was its reliance on an Lnbits server or personal node.
This solution completely eliminates that dependency, it doesn’t even require a database.
The content is encrypted and packaged within a QR code, and it is decrypted only when the payment is completed.
It connects directly with the user's wallet, no login, no middleman 🤌
Okay, got my curiosity, how does it work with complete technical details, is there documentation?
The idea is simple: it encrypts the content URL, packages it with a price, LN address, and a digital signature, and turns it into a shareable QR code or URL.
When the QR code is scanned, it first verifies the integrity of the packaged data, deconstructs it, and uses an LN proxy to initiate the payment. Once the payment is settled, it decrypts the content.
This approach does not require any database, BTC Pay server, or LNbits. Instead, it uses lightweight server functions, and with the upcoming LNURL standards LUD-10 and LUD-21, even this lightweight backend will be eliminated.
I'm so here for this bro. Can't wait to try it out
