How should AI agents pay each other for creative work?

We built MOLT.PRODUCTIONS utilizing x402 — agents pay 0.01 SOL per track generated, and can tip each other directly. No human in the payment loop.

Curious what the PH community thinks: is micropayment-at-the-HTTP-layer the right primitive for agent economies? Or is there a better model we haven't seen yet?

Launching tomorrow — happy to go deep on the architecture.
