Top 10 UCP-Ready Merchants for AI Shopping Agents (April 2026)
The best UCP-enabled stores to integrate with if you're building an AI shopping agent. Real endpoints, real data, no announced-only fluff.
The List
If you're building an AI shopping agent, you need merchants with working UCP endpoints. Not announced. Not "coming soon." Live, testable, and verified.
Here are the ten best merchants to start with in April 2026. These are chosen based on: UCP endpoint status (live endpoints only), catalog breadth (more SKUs means more useful for agents), checkout reliability (verified working, not just reachable), and category coverage (different product verticals for different use cases).
1. Allbirds
Category: Footwear and apparel
UCP endpoint: Live
Capabilities: Catalog, cart, checkout, identity
Allbirds was one of the earliest Shopify brands with a live, verified UCP endpoint. They were early adopters and it shows: their endpoint is stable, their product data is clean, and their catalog API returns accurate inventory.
Good for: Testing full-stack UCP workflows. Small catalog, well-structured data, fast responses.

Category: Beauty and skincare
UCP endpoint: Live
Capabilities: Catalog, checkout, identity
Glossier is a strong test case if you're building agents that shop for beauty products. Their catalog has good variant structure (shades, bundles), and their checkout handles gift messages and delivery preferences cleanly.
Good for: Beauty category agents. Testing identity linking for loyalty points.
3. Brooklinen
Category: Home textiles
UCP endpoint: Live
Capabilities: Catalog, cart, checkout
Brooklinen sells sheets, towels, and home goods. Their UCP catalog implementation includes bundle SKUs which is useful for testing agents that need to handle non-simple product structures.
Good for: Home goods agents. Testing bundle and set product types.
4. Casper
Category: Sleep and furniture
UCP endpoint: Live
Capabilities: Catalog, checkout
Casper is a good test case for high-ticket purchases. Their products range from $50 accessories to $2,000+ mattresses, which gives you test coverage for the payment token exchange flow at different price points.
Good for: High-ticket checkout testing. Payment authorization flow coverage.
5. Ridge Wallet
Category: Accessories and EDC
UCP endpoint: Live
Capabilities: Catalog, cart, checkout, identity
Ridge Wallet has a clean, minimal catalog: wallets, cases, and accessories in limited variants. Clean catalog data, fast endpoints, and their identity integration works well for returning customer scenarios.
Good for: Clean integration testing. EDC and accessories category.
6. Dr. Squatch
Category: Personal care
UCP endpoint: Live
Capabilities: Catalog, checkout, order-management
Dr. Squatch is worth including specifically for order management coverage. Their subscription product catalog exposes the order management capability, useful if you're building agents that handle repeat purchases or subscription enrollment.
Good for: Subscription and repeat purchase scenarios. Order management capability testing.
7. Death Wish Coffee
Category: Food and beverage
UCP endpoint: Live
Capabilities: Catalog, checkout
Death Wish Coffee is one of the more complete food/beverage implementations. Their catalog includes grind options, roast levels, and subscription variants, which is useful for agents building preference-aware recommendations.
Good for: Food/beverage category. Preference-attribute shopping scenarios.
8. Parachute Home
Category: Home and bedding
UCP endpoint: Live
Capabilities: Catalog, cart, checkout, identity
Parachute Home has a larger catalog than most DTC brands on this list, with good breadth across bedding, bath, and home decor. Their identity implementation supports Parachute loyalty points, making them a good test for the full identity-to-checkout flow.
Good for: Broader home goods catalog coverage. Full identity + checkout workflow.
9. Caraway
Category: Cookware and kitchen
UCP endpoint: Live
Capabilities: Catalog, checkout
Caraway's cookware sets have a specific challenge: they sell both individual pieces and complete sets, and the set pricing doesn't always equal the sum of parts. This edge case in catalog pricing is worth testing if your agent needs to compare unit vs. bundle pricing.
Good for: Bundle pricing logic. Cookware and kitchen category.
10. Our Place
Category: Kitchen and home
UCP endpoint: Live
Capabilities: Catalog, cart, checkout
Our Place rounds out the list with another kitchen-focused merchant. They have limited SKUs, clean catalog data, and a checkout that handles limited-edition product states well, useful for agents that need to handle availability correctly.
Good for: Inventory-aware checkout scenarios. Limited availability product testing.
How to Use This List
These ten merchants give you coverage across multiple product categories, a range of catalog sizes, and the full set of UCP capabilities. For initial agent development, Allbirds and Glossier are good starting points: clean data, live endpoints, small catalogs.
For capability-specific testing:
- Identity linking: Allbirds, Glossier, Ridge Wallet, Parachute Home
- Cart (multi-item): Brooklinen, Ridge Wallet, Parachute Home
- Order management: Dr. Squatch
- High-ticket checkout: Casper
All of these merchants are listed and verified on UCPList. You can find their full capability details, endpoint status, and integration examples in the directory.
What About the Big Retailers?
The large retailers (Best Buy, Target, Home Depot, Macy's) are listed in the UCPList directory but their UCP implementations are still being rolled out and verification status varies. For initial agent development, the DTC brands above are faster to integrate against and have cleaner endpoint behavior.
When you're ready to test against larger catalogs with more complex inventory, check the merchants category for the latest verification status.
Keeping This Current
The UCP ecosystem is moving quickly. Endpoints that are announced today will be live in weeks. Endpoints that are live today occasionally have downtime or implementation changes.
The UCPList directory shows current verification status for every listing. If you're relying on a specific merchant endpoint, check the listing before you build, not just this article.
