ScriptCipher · x402

Film-grade subtitle generation where every timestamp is cryptographically anchored. Pay 0.01 USDC per minute of processed dialogue to generate, sync, and sign .srt files via Base. Use it to gate premium content or provide tamper-proof transcripts for legal and archival videography. No subscriptions, just compute-on-demand.

The primitive.

full primer →

Access to the subtitle generation 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 moving from a 'mint' model to a metered 'usage' model, we capture the high-frequency nature of post-production. Each call triggers an HTS transfer transfer, turning the subtitle file into a paid asset that is verified upon delivery.
