AuraFlow · x402

$0.01 — Stream an infinite, procedurally generated ambient soundscape. No subscriptions; you pay per minute of audio generation. Using x402, listeners fund sound designers directly in real-time. The protocol meters high-fidelity stems, allowing developers to pay-per-sample to integrate these textures into their own games or apps via secure HTS transfer signatures.

The primitive.

full primer →

Access to the ambient music archives 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 primitiveShifts from 'ownership' (NFTs) to 'utility' (pay-per-minute/sample). This solves the friction of monthly music subscriptions for background noise and creates a new revenue stream for sound designers where every second of playback is a micro-settlement on Hedera.
