Protocol-Agnostic Infrastructure
Euler AI supports both UCP and ACP protocols, enabling seamless commerce flows across all major AI platforms. One integration, universal reach.
Supporting Open Commerce Standards
Euler infrastructure works with both UCP and ACP protocols, giving merchants access to all major AI platforms through a single integration.
UCP
A composable architecture developed by Google that creates a common language for consumers, agents, and businesses. Powers agentic commerce across Gemini and other AI platforms.
Key Features:
ACP
An open standard developed by OpenAI and Stripe enabling programmatic commerce flows. Powers Instant Checkout in ChatGPT while merchants maintain direct customer relationships.
Key Features:
One Integration, Universal Access
Euler's infrastructure abstracts away protocol complexity. Build once, and automatically support both UCP and ACP — reaching customers across Gemini, ChatGPT, Copilot, and future AI platforms without additional engineering work.
UCP: Composable Commerce Architecture
UCP provides a standardized set of capabilities and extensions that enable flexible, secure commerce integrations. Agents discover what's possible, negotiate capabilities, and execute transactions with cryptographic guarantees.
Core Capabilities:
UCP Secure Checkout Flow
UCP's AP2 Mandate system ensures AI agents complete purchases securely through cryptographic verification.
Discovery & Binding
Agent and merchant establish secure connection, verify identities, and agree on transaction capabilities.
Presentation & Mandate
User reviews order details and confirms. Agent generates cryptographic mandate proving authorization.
Submission & Verification
Mandate verified, payment processed securely, and order created with complete audit trail.
ACP: Instant Checkout Experience
ACP streamlines the purchase flow into a simple, agent-mediated experience. Users confirm intent, agents coordinate with merchants, and transactions complete seamlessly — all while merchants maintain ownership of customer relationships.
Checkout Flow:
ACP Transaction Flow
Programmatic handoffs between buyer, agent, merchant, and payment processor enable instant checkout.
