Not a video, but a live working example: I built TANSTAAFL — anti-spam email powered by Lightning. Strangers pay 100 sats to reach your inbox. If they don't pay, the email never arrives.

You can test it right now: send anything to mailto:niko@tanstaafl.email. You'll get a challenge email back with a Lightning invoice. Pay 100 sats, your email goes through.

The AI agent part is how the system monitors, triages, and handles the email pipeline autonomously. The Bitcoin part is the actual economic mechanism — attention has a price, and Lightning makes micropayments practical enough to enforce it.
