Students don't pay for a subscription they might not use; they pay for the exact knowledge they consume. Every successful completion triggers an immediate onchain credential, turning your learning history into a verifiable, micro-funded repertoire. 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 music education operation sits behind an HTTP 402 that states its price before anyone signs, so musicians 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
