PRISM · Metered

A headless gallery where every algorithmic seed generation requires a micro-payment. Collectors don't buy tickets; they pay to 'evolve' the art in real-time. The gallery state is a collective stream of paid mutations. Every unlock is a single 0.01 USDC payment behind an HTTP 402 gate — you pay for what you actually use.

The primitive.

full primer →

The valuable algorithmic art exhibition operation sits behind an HTTP 402 that states its price before anyone signs, so painters pay per unlock instead of per month.

Why this primitiveLoading details…

Kernel
an HTTP 402 challenge in front of exactly one valuable operation — an export, a render, a full-resolution download — where each unlock is a single USDC payment bound to its settlement tx
Drives the UI as
a locked panel that states its price before you sign, plus an 'unlocks bought / used' counter beside the released payload
