GenPress · x402

A headless canvas for generative brushes. Artists deploy scripts; users pay 0.01 USDC to trigger a 'render' call. Each HTS transfer signature generates a unique, deterministic seed on-chain. Pay-per-stroke or pay-per-high-res-export, with the facilitator settling the artist's royalties instantly to their Magic Link email sign-in. Use our API to embed living art into any site, metered by the view.

The primitive.

full primer →

Access to the generative art 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 primitivex402 transforms generative art from a one-time NFT sale into a recurring service. By gating the 'render' function, artists monetize the execution of their code, not just the static output. This allows for 'streaming' art where every frame or interaction is a micro-transaction.

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.
