FitCheck · x402
A cryptographic proof-of-fit engine. Users pay 0.05 USDC per high-fidelity render to verify garment draping against their anonymized body scan. Brands pay a recurring 0.01 USDC 'verification fee' per session to eliminate 'bracket ordering' returns. Every try-on is a paid, verifiable event that generates a unique HTS transfer signed claim of fit accuracy.
The primitive.
Access to the try-on verification 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 primitiveCurrent virtual try-ons are low-stakes and inaccurate. By attaching a micro-cost to the render, we shift the value from a 'fun filter' to a 'financial utility' that replaces the $15 cost of a return shipment with a $0.05 verification fee.
