The UCP discovery endpoint provides supported protocol versions, service endpoints, catalogue capabilities, cart capabilities, checkout capabilities, fulfilment capabilities, order capabilities and payment handlers.

### Typical Agent Flow

## For Personal Shopping Assistants and Buy-for-Me Agents

If the agent can use Shopify's recommended agentic shopping tools or Shop Pay-based buyer approval flow, it should prefer those methods over screen-scraping or automating the storefront manually.

Agents should preserve buyer approval at every payment step and must not handle payment details directly unless the payment method and protocol explicitly allow this with buyer consent.

## Platform

This store is built on Shopify.

Shopify supports agentic commerce through structured catalogue access, UCP discovery, cart and checkout capabilities, and buyer-approved payment flows.
