I built this as a Garage Project over the weekend. https://x402.backpac.xyz/

Still working on refining things, but let me know your thoughts.

Cheers.

These client-side solutions don't work in real life. For details, here is claude giving real bypass scripts and some info: https://gist.github.com/freakynit/4ba5c1a6ff1fa935dd01d873d0...

Rule of thumb: never rely on client-side-only checks for any verification. All client-only checks can be spoofed. There might be extremely specific cases where this is not true, but, mostly, it is.

It doesn't work that way. What you've documented won't work.
