Agentic Commerce

Is Your Store Ready for AI Shopping Agents?

Q: What is the Universal Commerce Protocol (UCP)?

UCP is an open, decentralized protocol backed by Google and Shopify that lets AI agents discover and transact with any online store through a /.well-known/ucp manifest. It works similarly to robots.txt but for commerce capabilities.

Q: What is the Agentic Commerce Protocol (ACP)?

ACP is a platform-mediated protocol created by OpenAI and Stripe. Merchants register their catalogs with OpenAI, and AI agents like ChatGPT can recommend and facilitate purchases through Stripe-powered checkout.

Q: Do I need to support both UCP and ACP?

Supporting both protocols maximizes your reach. UCP covers Google-ecosystem agents (Gemini, Copilot) while ACP covers ChatGPT Shopping. Dual-protocol merchants see up to 40% more AI-driven traffic.

Q: How long does it take to become UCP or ACP compliant?

Basic UCP compliance can be achieved in a few hours by adding a /.well-known/ucp manifest. ACP requires registering with OpenAI and integrating Stripe, which typically takes a few days. Our free readiness reports give you a step-by-step plan.

Q: Will AI shopping agents replace traditional search-based shopping?

AI agents will complement rather than replace traditional shopping. However, analysts predict up to 20% of online commerce could be agent-driven by 2030. Early adopters will have a significant competitive advantage.

AI agents powered by Google, OpenAI, and others are reshaping online commerce. The Universal Commerce Protocol (UCP) and Agentic Commerce Protocol (ACP) enable these agents to discover, recommend, and buy from your store.

The Two Protocols

What is Agentic Commerce?

UCP is a decentralized, open protocol. Stores publish a /.well-known/ucp manifest that AI agents can discover automatically — no platform registration required. Think of it as robots.txt for commerce. Any AI agent (Gemini, Copilot, and more) can read your catalog, check prices, and initiate transactions directly.

Agentic Commerce Protocol (ACP)

ACP is a platform-mediated protocol. Merchants register their products with OpenAI and integrate Stripe for payments. ChatGPT Shopping then surfaces your products to users as contextual recommendations, complete with one-click checkout powered by Stripe.
