SonicBond · x402
Pay 0.01 USDC to cryptographically align a high-fidelity audio track to a video frame and generate a permanent 'Sync-Lock' hash. Every alignment call pays the sound engineer or the AI model instantly, creating a verifiable chain of custody for ADR and sound design. Payment is the proof of synchronization; no settlement, no sync.
The primitive.
Access to the audio synchronization engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so videographers — or the agents working for them — pay per query and get a HashScan receipt every time.
Why this primitiveBy turning 'synchronization' into a metered x402 transaction, you move from static NFT minting to a functional service. The micropayment acts as the trigger for the alignment algorithm, ensuring creators are paid per edit cycle rather than a flat, easily pirated fee.
