If you've used ChatGPT or Gemini to find products, you've probably noticed the results are inconsistent. Sometimes rich product cards with images and prices. Other times hallucinated products or outdated info.
The difference comes down to whether the store serves structured data via the Universal Commerce Protocol (UCP): the open standard Google and Shopify launched in January.
I built a demo showing the consumer-facing side of this.
You can type natural language queries and see how an AI agent:
- Matches intent to real products from a live catalog
- Presents rich cards with images, real-time pricing, ratings, stock
- Provides direct purchase links (no marketplace)
It's essentially what AI-mediated shopping looks like when it works properly vs. when the AI is guessing from scraped page content.
Built this as part of a project making WooCommerce stores UCP-ready. Curious what this community thinks about the agentic commerce trajectory: is this going to be as big as the protocol backers (Google, Shopify, Stripe, Visa) think?
