ITERATE · x402

Pay-per-seed-variation for generative explorers. Instead of paying for a final output, users stream 0.01 USDC per iteration to the artist's wallet to compute and reveal the next seed in the latent space. Each payment triggers an on-chain event that logs the specific parameter set, allowing users to 'purchase the evolution' of a piece frame-by-frame. Payment is the literal shutter button for the generative engine.

The primitive.

full primer →

Access to the generative art iterations 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 primitiveTraditional minting is too heavy for iterative exploration. x402 enables a 'metered discovery' model where the user pays for the compute and the artist's algorithm in real-time. It transforms the viewing experience into a transactional dialogue between the collector and the code.

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.

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.
