Core Architecture Principles

Built specifically for high-reliability, zero-hallucination agentic commerce.

🛡️

Explicit Confirmation Guardrail

Models are enforced via strict MCP schemas to execute quote_order first, show exact pricing, and require explicit user consent before calling create_order.

💳

Provider-Supplied Checkout

Zayuno never stores credit card details. Orders return verified provider checkout links where customers complete payment directly on the provider's payment page.

⚡

Cryptographic Webhooks

Real-time synchronization between merchant backends and AI clients via cryptographic HMAC SHA-256 signatures, transitioning order states instantaneously.
