TrueThread · x402

A pay-per-query verification engine for luxury resale. Users or AI-shopping agents pay 0.01 USDC to query the vault's high-fidelity textile database. Each micropayment triggers a Base-settled authenticity certificate, turning every 'legit check' into an instant, metered revenue stream for verified archivists.

The primitive.

full primer →

Access to the authenticity 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 primitiveAuthenticity is currently a high-friction service. By atomizing the cost to $0.01 per check via x402, we enable high-velocity 'micro-appraisals' and allow AI aggregators to programmatically verify listings before they reach consumers.
