Lume · x402

Gallery-grade digital matting and AR framing as a metered service. Creators embed a 'Lume' call into their mints; collectors pay $0.01 USDC per viewing session to render the piece in a high-fidelity, environment-aware digital frame. No monthly subscriptions for collectors—just a penny to see the art properly dressed for the screen.

The primitive.

full primer →

Access to the digital framing services 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 pivoting from a 'marketplace' to a 'metered rendering service,' the payment becomes the primitive for visual fidelity. Moving the cost to a pay-per-render model allows artists to offer 'free' art that generates continuous micro-yield every time a collector displays or showcases the work.
