LoopVault · x402
A high-fidelity stem library where every 'Download' or 'Drag-to-DAW' action triggers a 0.05 USDC micropayment directly to the producer. By integrating x402, LoopVault removes the friction of monthly subscriptions and legal complexity. You pay exactly once per loop, instantly acquiring a cryptographically signed usage rights receipt tied to the Base transaction hash. It turns every sound into a metered asset for both human producers and AI music generators.
The primitive.
Access to the loop exchange engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so musicians — or the agents working for them — pay per query and get a HashScan receipt every time.
Why this primitiveTraditional loop sites use predatory subscription models where creators get pennies. x402 enables 'Pay-Per-Stem' (PPS) utility, allowing bedroom producers to monetize individual sounds without a middleman taking 50%. It also solves the 'AI Training' problem by providing a technical gate for agents to legally ingest licensed audio one sample at a time.
