ChromaMeter · x402

A distributed LUT registry where cinematographers pay 0.01 USDC to unlock professional grade-stacks. Every 'Apply' action is a micro-transaction that settles on-chain, creating a transparent revenue stream for colorists while providing filmmakers with verifiable, production-ready aesthetic profiles. Pay per frame-match or per LUT-pull via signed HTS transfer authorization.

The primitive.

full primer →

Access to the color grading engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so videographers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveShifts color grading from a static software license to a metered 'aesthetic-as-a-service' model, rewarding technical precision at the individual clip level.
