ChatGPT, Google AI Mode, and Perplexity answer shopping questions using structured product feeds, not your storefront HTML. UCP (Universal Commerce Protocol) is the open standard for that catalog format. UCP Feed publishes your active Shopify catalog as a UCP-compliant feed at a stable public URL, and publishes a UCP business profile at the standard .well-known/ucp location so agents can discover your capabilities. Product changes refresh the feed within seconds through Shopify webhooks. The feed is served with a five-minute public cache, a one-hour CDN cache, and an ETag for conditional 304 responses. Install from the Shopify App Store and approve two read-only scopes: read_products and read_inventory. We do not write to your products, theme, or settings, and we do not access orders or customers. We do not promise placement in any specific agent results, sales lift, or ranking improvement. The technical fact is that your feed is published; indexing decisions belong to each agent. Uninstalling immediately revokes our OAuth token.
