Pigment · x402

$0.01 — inject heritage into your canvas. A peer-to-peer hex-code market where every 'Apply Palette' action triggers a direct USDC settlement to the original color theorist. No subscriptions, just sub-cent micro-licensing for professional illustrators and generative artists seeking high-fidelity aesthetics. Use the HTS transfer flow to instantly unlock unique .ASE and .CLR files via signed intent.

The primitive.

full primer →

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

Why this primitiveBy commoditizing the 'Palette' at the sub-cent level, we transition from 'free inspiration' to a paid 'style-injection' economy. x402 handles the high-volume, low-value nature of color data that traditional gas fees would kill.
