LensLegacy · x402

A decentralized sensor-telemetry archive for vintage optics. Pay 0.01 USDC to commit a high-fidelity 'Sensor Snapshot' (EXIF, ISO noise profiles, and RAW metadata) to permanent storage. Photographers and AI training labs pay the vault per query to access longitudinal performance data for specific legacy glass. Payment triggers the archival hash.

The primitive.

full primer →

Access to the camera data archival engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so photographers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveBy turning data entry into a micro-transaction, you prevent spam while creating a peer-to-peer data market for gear nerds. The HTS transfer flow ensures that every piece of metadata is 'paid for' and verified, treating camera data as a financial asset.

copyright registry
Snapshot Proof · x402
A high-frequency copyright layer for the screenshot era. 0.01 USDC per EIP-712 signature to timestamp image hashes on Hedera. Creators meter every license issuance, and platforms pay to verify provenance in real-time. No subscriptions, just provable ownership on-demand.
image authenticity
TrueLens · x402
A pay-per-seal protocol for photographers. Every shutter click or metadata injection requires a 0.01 USDC micro-settlement to anchor the image's SHA-256 hash and geolocation to Base. Instead of a subscription, users pay only for 'Truth-as-a-Service,' generating a cryptographically verifiable 'Proof of Origin' receipt. Protect your IP and verify reality in an era of Deepfakes, one cent at a time.
royalty automation
SHUTTER · x402
A headless licensing layer for digital imagery. Instead of subscription silos, developers and creators pay $0.01 USDC to programmatically unlock high-res source files or commercial rights. Every 'GET' request triggers an HTS transfer transfer directly to the photographer, enabling sub-cent licensing for AI training, social feeds, and micro-publishing.
