Jury · x402

A hyper-competitive photo critique engine where feedback is a paid asset. Photographers pay 0.01 USDC to push their work to the 'Jury'—a curated feed of high-rep peers. Critiquers earn direct micro-bounties for every actionable review, verified by on-chain sentiment logic. No vanity likes, no bots—only skin in the game for real aesthetic growth.

The primitive.

full primer →

Access to the community critique 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 primitivex402 transforms 'likes' into micro-transactions. By charging for the upload and rewarding the critique, it solves the 'low-effort feedback' problem common in free communities. Payment ensures the attention is real.

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.
