SONIC FLOW · x402

$0.01 — Every audition is a micro-license. Pay to listen, pay to drag-and-drop. Samples are metered at the DAW level via HTS transfer. No subscriptions, just raw utility for producers and autonomous AI composers who need high-fidelity stems for real-time generative scoring. Settlement triggers a Hedera transaction id, instantly routing royalties to the creator's wallet.

The primitive.

full primer →

Access to the music marketplaces 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 primitiveBy shifting from a bulk purchase model to a per-audition/per-download model, the marketplace captures value at the moment of inspiration. It removes the friction of 'credit packs' and enables machine-to-machine commerce where AI agents can buy samples mid-track.

Sample Chain Marketplace

Create a decentralized marketplace for verified, licensed music samples with automatic royalties.

sample tracking

Provenance · x402

A sub-cent attribution layer for sound design. Producers pay $0.01 USDC to instantly unlock high-fidelity stems and secure a cryptographically signed provenance receipt. Every time a sample is previewed or dragged into a DAW, the facilitator settles a micropayment directly to the original creator's Magic Link email sign-in. No subscriptions, just pay-per-sample flow for the agentic music economy.

remix licensing

A 'Pay-per-Stems' protocol where remixers stream high-fidelity project files for 0.05 USDC per download. Every stem download triggers an immediate HTS transfer settlement to the original producer's wallet. Final remix uploads are gated by x402 signatures, ensuring the licensing fee is burned into the metadata before the track can be minted or played. licensing is no longer a contract; it's a micropayment primitive.

beat collaboration

BeatCommit · x402

A real-time rhythmic session layer where every MIDI pattern, drum hit, or sample flip is committed as a cryptographically signed stem. Producers pay 0.01 USDC to 'Drop' a loop into the shared master or 'Stem-Out' a high-quality bounce. Payments serve as the immutable proof-of-contribution, creating a financial trail of authorship that prevents ghost-producing and ensures royalty attribution at the primitive level.
