Nexartis or a tenant site requests a Yanez challenge and receives QR data plus a creator-only status URL.
// Nexartis × Yanez
Human assurance for the agentic transaction layer.
Nexartis composes Yanez proof ceremonies into high-value agent flows: onboarding, delegated payments, payment intent authorization, and context-bound approvals. The result is a clean service boundary where humans authorize once, agents act within bounded scope, and verifiers retain cryptographic evidence.
// Architecture
QR ceremonies that travel across origins.
The QR service can generate challenges from the deployed Yanez site or from an external display site. Callback URLs stay anchored to the Yanez Worker, while status URLs remain creator-only so the final proof routes back to the site that initiated the flow.
Nexartis app → Yanez QR Worker → Yanez mobile capture → Verified status/token
Display
The QR can be rendered on the Yanez site or embedded on another origin with CORS-enabled API access.
Capture
The Yanez app performs live photo capture and signs the exact challenge or canonical preapproval blob.
Return
The Worker verifies BLS, address binding, and scope, then exposes results through the protected status URL.
