UCP Protocol

The Universal Commerce Protocol (UCP) is an open standard for AI agent commerce — enabling product discovery, cart management, and checkout across any merchant platform.

What is UCP?

The Universal Commerce Protocol (UCP) is an open standard designed to give AI agents a consistent, structured way to interact with any commerce platform. Where x402 focuses on API payments and AP2 is tied to Google’s ecosystem, UCP aims to be the universal layer for AI-driven e-commerce — working across Shopify, WooCommerce, custom storefronts, and any merchant platform.

How It Works

UCP defines a set of standardized operations that any merchant can implement:

  1. DISCOVER — agent searches for products across merchant catalogs
  2. GET_PRODUCT — agent retrieves detailed product information
  3. ADD_TO_CART — agent adds items to a shopping cart
  4. UPDATE_CART — agent modifies quantities, applies coupons
  5. CHECKOUT — agent completes purchase with payment
  6. TRACK_ORDER — agent monitors shipment and delivery
  7. RETURN — agent initiates returns or exchanges

Key Technical Details

  • Protocol Type: REST-based API standard with JSON payloads
  • Merchant Integration: Standardized endpoints any platform can implement
  • Payment Agnostic: Works with crypto (USDC, ETH) and traditional rails
  • Authentication: API keys with delegated agent permissions
  • Platform Support: Shopify, custom stores, marketplace platforms

Use Cases

  • Headless AI Commerce — agents shop across any platform without browser automation
  • Multi-Platform Price Optimization — compare and buy across different stores
  • Automated Inventory Management — AI-driven restocking from multiple suppliers
  • White-Label Agent Shopping — build branded shopping agents for your customers
  • B2B Procurement — enterprise purchasing across supplier catalogs

Why It Matters

UCP solves the fragmentation problem in AI commerce. Instead of building custom integrations for every e-commerce platform, agents use one protocol to interact with any UCP-compliant merchant. This is the HTTP of AI commerce — a universal standard that any merchant can adopt.
