STREET SEAL · x402
A high-fidelity street art archive where every high-resolution 'capture' or 'view' of a mural triggers a 0.01 USDC micropayment directly to the artist's wallet. Users sign a permission to unlock geographic location data and professional-grade documentation of fleeting public works, ensuring the creator gets paid for the preservation of their physical labor long after the wall is buffed. Free to browse thumbnails; 0.01 USDC to unlock the permanent digital twin.
The primitive.
Access to the public mural documentation 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 primitivePublic art is historically difficult to monetize once the work is finished. By metering access to high-res documentation and provenance data via x402, we turn passersby into micro-patrons and incentivize the archiving of ephemeral street art through a pay-per-view model that bypasses traditional gallery gatekeepers.
