VERNISSAGE · x402

A high-fidelity digital archive for art fairs where collectors pay a nominal USDC fee to unlock the full 'Provenance Record' of featured works. Collectors pay 0.01 USDC to view high-res scans and pricing history, while agents and art-advisors pay to programmatically pull gallery rosters. Each unlock triggers a Base transaction, ensuring fair distribution to the hosting fair and featured artists.

The primitive.

full primer →

Access to the event art listings 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 primitiveEvent catalogs are currently static PDFs or ad-cluttered sites. x402 turns every gallery booth into a micro-revenue node. By gating high-res assets behind a $0.01 sign-to-pay, it filters for high-intent leads and creates a perpetual royalty stream for the event organizer whenever the 'digital twin' of the fair is accessed.
