Spatial Pin · x402

Pay-per-view AR spatial layers. Users pay 0.01 USDC to pull encrypted AR textures and geometry from IPFS for local rendering. Creators earn per 'eye-gaze' unlock, ensuring a durable economy for digital street art and immersive installations without ads or tracking.

The primitive.

full primer →

Access to the AR art content storage 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 shifting from free storage to pay-per-retrieval, storage costs are offset by user engagement. x402 handles the high-frequency/low-value transactions needed to unlock high-res assets in real-time as a user moves through a physical space.

art ownership tracking
HardTrace · x402
An on-chain verification layer where creators and galleries pay 0.01 USDC to append or verify high-fidelity provenance events. Trade paper trails for a micro-paid, immutable ledger of truth.
generative art minting
Gen-Seed · x402
A headless seed-to-string engine where 0.01 USDC triggers a unique generative iteration. Instead of a heavy upfront minting fee, users pay per 'Evolution Sign-off.' Artists deploy logic; collectors pay per high-fidelity render, receiving a Hedera transaction id as proof of unique generation. The payment is the shutter click.
gallery exhibition tracking
Exhibit · x402
Provenance is a living ledger, not a static database. Exhibit pays the artist 0.01 USDC every time a curator, insurer, or buyer pulls a verified exhibition history or updates a physical location tag. Turn the 'paper trail' into a real-time revenue stream for estates and digital creators.
