About this tool

UCP is Google and Shopify's emerging interoperable feed standard for agentic shopping. This validator parses your UCP feed, confirms field types, identifier formats and required attributes, and flags issues before Google rejects the catalog.

UCP vs ACP

UCP (Universal Commerce Protocol) is Google and Shopify's interoperable counterpart to OpenAI's ACP. The two specs cover the same ground but use different field names and slightly different schemas. Most stores will eventually need both — UCP for Google AI surfaces (Gemini, AI Overviews, Shopping), ACP for OpenAI (ChatGPT, Operator).

Where UCP gets stricter than Google Shopping

  • • Currency must be a 3-letter ISO 4217 code (not just "USD" or "$")
  • • Availability enum is narrower (in_stock, out_of_stock, limited, preorder)
  • • return_policy_url and shipping_policy_url are agent-recommended (Google Shopping treats them as optional)
  • • inventory_count is needed for "limited stock" badging in AI shopping surfaces
