ClearVue · x402

A high-fidelity proofing engine where clients pay-per-view to de-blur or remove watermarks from high-res asset previews. Photographers upload to IPFS, and each 'reveal' triggers a 0.01 USDC x402 stream to the creator. No more manual invoicing for small-batch selection; the metadata unlock is the transaction.

The primitive.

full primer →

Access to the image watermarking 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 moving from static protection to 'metered visibility,' x402 turns the proofing process into a high-velocity revenue stream. It eliminates the friction of bulk licensing for clients who only need specific shots, while ensuring creators are compensated for every single impression of their raw work.

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.

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.
