$0.01 — pay-per-layer. Turn photo editing into a micro-transactional marketplace where every professional transform—color grade, mask, or retouch—is a paid 'pull' from a collaborator's private preset library. Each edit is an atomic transaction signed by your Magic Link email sign-in, instantly settling revenue to the contributor and committing the delta to the chain. No subscriptions, just pay for the specific human or AI expertise applied to your canvas.
The primitive.
Access to the collaborative editing engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so photographers — or the agents working for them — pay per query and get a HashScan receipt every time.
Why this primitiveBy shifting from 'tracking history' to 'paying per operation,' the app turns a passive log into an active revenue engine for retouchers. x402 handles the high-frequency, low-latency settlement required for multi-layer collaborative workflows.
