Native compatibility with leading Agentic engines
The Universal Translator
One integration. Both protocols. Zero compromise.
Don't choose between Google and OpenAI. We translate your store into both standards automatically.
Protocol Compliance
Fully compatible with the official specifications
Multi-Agent Support
We handle the complexity of the Format Wars. Whether it's Google's UCP or OpenAI's ACP, our middleware ensures your products are formatted correctly for every agent.
Google Gemini (UCP)
Your products are automatically formatted according to the Universal Commerce Protocol specification. Appear in Gemini shopping results and Google Search AI Overviews.
ChatGPT / OpenAI (ACP)
Simultaneously formatted for the Agentic Commerce Protocol. Enable instant checkout inside ChatGPT conversations without any additional configuration.
Make your checkout agent-ready
Implement the UCP & ACP specification to configure your checkout for agentic commerce, so that any compatible agent can securely initiate checkout.
Here are some options to check out:
REST and MCP compatible
Publish your checkout configuration with a traditional API or MCP. UCP & ACP work with any integration pattern and technology stack.
Works with your existing infrastructure
Create and control agent-facing endpoints that integrate with your existing commerce backend and payment processor.
Secure and PCI compliant
Securely pass payment credentials from your buyers to AI agents, without exposing underlying payment credentials.
Don't Get Caught in the Middle
Google speaks UCP. OpenAI speaks ACP.
The Format Wars have started. Google wants merchants to speak UCP. OpenAI wants merchants to speak ACP. If you build for one, you lose the other.
This is VHS vs. Betamax for AI Shopping
Merchants are going to hate this. They will say: "Wait, I have to build one integration for Google and a DIFFERENT one for ChatGPT? No way."
UCP Commerce handles the translation layer so you never have to worry about breaking changes. Be visible on Gemini AND ChatGPT instantly.
UCP (Google)
Backed by Google & Shopify. Powers shopping on Gemini and Google Search.
ACP (OpenAI)
Backed by OpenAI & Stripe. Powers Instant Checkout inside ChatGPT.

The 4 Pillars of Agentic Commerce
Whether you use UCP (Google) or ACP (OpenAI), the ecosystem relies on these four actors working in sync.
Buyer (User)
Initiates intent ('Buy me boots') via ChatGPT or Gemini. Grants the 'Cart Mandate'.
AI Agent
Orchestrates the discovery. Translates natural language into UCP/ACP protocol queries.
Merchant (You)
The 'Merchant of Record'. Receives the structured order via UCP Commerce middleware.
Payment (PSP)
Handles the 'Shared Payment Token'. Validates the AP2 cryptographic proof.
Frequently Asked Questions
Everything you need to know about UCP Commerce
Do I need to migrate off WooCommerce?
No. We are a layer on top. UCP Commerce connects to your existing WooCommerce, Magento, or custom stack API without requiring any migration. Your current infrastructure stays intact.
Is this secure?
Yes. We use the AP2 (Agent Payments Protocol) standard. We never store raw credit card data. All payments are handled through secure, tokenized mandates with cryptographic proof of user consent.
Which AI agents support this?
Currently Google Gemini (Alpha) and custom MCP Agents support UCP. OpenAI support is coming in Q4 2026. The protocol is open-source and any AI platform can implement it.
How long does integration take?
Integration takes less than 5 minutes. Simply configure your store URL and platform type in our config file, and we handle the rest. No code changes required.
Can I use my existing payment processor?
Yes. UCP Commerce works with any payment processor that supports AP2. Stripe is the first compatible PSP with Shared Payment Tokens, and more providers are being added.
