FocusProof · x402
A forensic layer for professional photography. For 0.01 USDC, lock a high-resolution 'Focus Signature' into the Base ledger, attaching lens telemetry and focal plane depth to an image's hash. Buyers or publishers pay 0.01 USDC to verify the focus integrity, ensuring the image is optically captured and not a post-processed generative hallucination.
The primitive.
Access to the focus tracking 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 focus metadata into a paid primitive, we create a barrier against AI-generated spam and a verifiable receipt for technical excellence. The micropayment acts as a 'digital notary' for optical truth.
