AI has already been the invisible backbone of modern commerce, powering search and recommendations. But with the launch of the Agentic Commerce Protocol (ACP), it’s stepping into a completely new role: not just optimizing the shopping experience, but doing the shopping itself.
For e-commerce managers and developers, that’s a game-changer. The introduction of ACP feels like one of those moments when technology changes the script – the same kind of leap as from typing DOS commands to using Windows. This time, the shift is happening in commerce, and the goal is to turn a user's shopping experience into a conversation.
Research shows that 74% of consumers already prefer interacting with chatbots over human customer service agents. And now it’s no longer about talking to a chatbot, but about a chatbot shopping for you. Instead of you searching, scrolling, and comparing, you’ll just say, “Find me a minimalist lamp under €50,” and an AI assistant will do the rest: browse, evaluate, and even complete the checkout.
That brings a big question: what does the shift mean for merchants, developers, and customers? To understand that, let’s start by looking at what the ACP actually is.
What Is Agentic Commerce Protocol (ACP)?
ACP is a new standard introduced by OpenAI and Stripe that lets AI agents (like ChatGPT) actually buy items on your store. It’s the foundation for AI-driven shopping where an AI assistant can browse products, compare prices, and go all the way through checkout without any manual clicks.
Such a checkout is called Instant Checkout, and it’s a breakthrough feature powered by ACP. It enables users to finalize the purchase directly within ChatGPT, without leaving out for external sites. All happens inside ChatGPT – through natural conversations.
Instead of humans adapting to digital interfaces, digital systems are now adapting to human language. It’s not just another tool or API update – it’s the beginning of a new layer in commerce, where conversation becomes the interface.
The protocol allows AI agents to interact with online stores directly so that AI can browse, compare, and buy autonomously. And because it’s open, not proprietary, developers can start experimenting right away and contribute to the open source community.
Why Does ACP Matter for Your Business?
With the Agentic Commerce Protocol, AI becomes a new sales channel. Instead of waiting for users to click or scroll, you’ll soon be serving a new kind of customer interface: intelligent agents making purchases on behalf of users.
That means merchants will sell directly to AI assistants like ChatGPT, integrated into everyday tools and devices. Imagine it as a new layer of discoverability: not search engine optimization, but AI optimization. To be visible in this new landscape, merchants will need their product data structured and accessible enough for AI to understand and act on.
For early adopters, this is a unique moment. The first stores that are AI-ready will stand out – they’ll show up in every “ChatGPT checkout” demo, every integration test, every AI-powered product recommendation. In short, they’ll gain merchant visibility in the next generation of shopping experiences.

The Future of E-Commerce
For years, online shopping has meant clicking buttons, typing in search bars, and navigating endless menus. Now AI turns this into a conversation. Introducing the Agentic Commerce Protocol points to a clear direction: online shopping becomes collaborative, intuitive, and… human in its interaction style.
Those who start building and experimenting today will shape how this future looks tomorrow. The era of AI commerce isn’t coming – it’s already here.
Building AI Commerce With Nimara
At Mirumee, we’re already implementing ACP in Nimara Storefront. The integration marks the first step to making AI commerce not a concept, but something you can actually experience.
Your customers are already starting to use AI more and more. That's why we're bringing the Agentic Commerce Protocol to Nimara Storefront – to unlock the next generation of AI-powered shopping experiences. We're among the first to make it real, and we couldn't be more excited about what's coming next.
Grzegorz Derdak, Team Leader and Frontend Engineer at Nimara
With Nimara, we’re creating the foundation for autonomous shopping – a reality where Instant Checkout isn’t a demo, but a real interaction between AI and your store. It’s commerce that can be processed through natural language securely, instantly, and without friction.
To enable smooth interaction through ChatGPT, we are working on integrating ACP as per the specifications proposed by OpenAI and Stripe. That means extending Nimara-ecommerce with new REST API endpoints:
/product_feed- for retrieving available products/checkout_sessions- for managing checkouts and orders.
Join the First Wave of AI-Driven Commerce
The shift toward AI commerce is already underway. The tools are here, the technology is real, and the first implementations are happening now.
We’re inviting the first merchants to implement the Agentic Commerce Protocol with Nimara Storefront. If you want to explore how agentic commerce can boost your store’s visibility, performance, and future readiness, now is the time to start.
