$0.01 — Protect audio assets instantly. Every time an AI scraper, producer, or platform requests the 'Proof of Origin' data for a track, you receive a micropayment. Payment triggers the verified cryptographic signature that authenticates your ownership and licensing rights on-chain. Turn copyright verification from a legal hurdle into a high-frequency revenue stream.

The primitive.

full primer →

Access to the copyright protection 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 watermarking is passive; this makes it active. By metering the verification process, creators are paid every time their work is audited or ingested by external systems. x402 handles the millions of tiny transactions that occur when AI models train on or platforms scan large libraries.

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
STEMS · x402
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.
