$0.01 — Burn accessibility into the chain. Pay-per-frame to generate, verify, or hard-code high-fidelity subtitles. Creators sign HTS transfer permits to pull captions from a global vault, while AI agents pay x402 fees to 'read' video metadata for search indexing. Settlement guarantees the translator or original captioner is paid every time a viewer toggles a language layer.

The primitive.

full primer →

Access to the captioning 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 primitiveReframes captions from a static NFT asset to a utility-metered stream. x402 allows for per-second or per-request billing, making sub-layer access a fluid economic activity rather than a one-time purchase.
