HueLock · x402

A digital color-mixing console where every 'eyedropper' extraction and palette generation requires a 0.01 USDC micro-settlement. Instead of static NFTs, designers pay per precise HEX/RGB derivation secured by the protocol. A unique HTS transfer signature locks the provenance of a specific shade to a designer's wallet, creating a cryptographically verifiable 'proof of discovery' for original textile hues. Metered color theory for the agentic fashion era.

The primitive.

full primer →

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

Why this primitiveBy shifting from lumpy NFT mints to pay-per-extraction, we turn color exploration into a high-frequency, low-friction utility. The protocol ensures that every 'pick' is a recorded event on Hedera, effectively timestamping creative IP at the moment of inspiration for a fraction of a cent.
