The primitive.

One 0.01 USDC payment turns the illustrator community record into a signed certificate painters can email, attach or archive — and the page proves who signed it without asking anyone to trust the server.

The payment is the shutter click. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.
artwork license management
Atelier · Paid Certificate
A high-frequency licensing gateway where digital assets are metered by the millisecond. Each glance or API call triggers an EIP-3009 transfer, returning a Base tx hash as a cryptographically verifiable proof-of-usage. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.
programmable artwork framing
BORDERLINE · Paid Certificate
A programmable border-engine where every aesthetic shift is a transaction. Use the QUIP primitive to meter 'Gaze-Based Evolution' (auto-shifting frames based on how many wall-clocks pass) or 'Oracle-Linked Skins' (weather/price/time-of-day) where each asset state-change is a paid, verifiable event. Pay to re-frame your collection for a specific gallery mood. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.
