Chromastream · x402

A decentralized Look Up Table (LUT) library where cinematic grading profiles are metered by the frame or the download. Instead of buying static packs, editors stream professional grade-data directly into their timeline, paying 0.01 USDC per application via x402. Every LUT 'pull' triggers an instant micro-settlement to the colorist, turning creative profiles into autonomous, revenue-generating assets.

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 filmmakers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveTransforms color grading from a one-time file purchase into a utility-based service. By using x402, it prevents mass piracy of LUT files; if you want the grade on a new project, you sign a 0.01 USDC event. This aligns the cost of production with the volume of use.
