CHROMA · x402

A professional-grade LUT extraction and application engine where users pay 0.01 USDC to instantly apply premium cinema-grade color science to their footage or export a mobile-ready filter. Each grading operation is an onchain event, ensuring creators get paid per frame processed or per preset unlocked.

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 from bulky NFT speculation to a high-velocity utility model. By charging per 'Apply' or 'Export', it turns color grading into a metered service compatible with both human hobbyists and automated AI video workflows.
