Integration Example
// Merchants participate in Universal Cart via UCP checkout.
// Google acts as the orchestration layer — agents add items to
// the cart, then Universal Cart handles cross-merchant checkout.
// As a consumer:
// Search for products → "Add to cart" → Check out with Google Pay
// As a merchant (via UCP):
const manifest = await fetch('https://your-store.com/.well-known/ucp').then(r => r.json());
// Universal Cart will discover your UCP endpoint and route checkout through it.Category

Reliable endpoint. We run automated conformance checks weekly and they pass consistently. The identity linking spec is fully implemented.

Good UCP support. Endpoint is stable and well-documented. The only minor friction was rate limits during initial testing — easy to request an increase.
