How Universal Checkout Works

Under the hood, Rye validates product data, handles shipping and tax, and submits the order to the merchant. This diagram shows the steps we automate for you.

​
The Challenge

Building commerce into AI apps isn’t just about linking to a product page. Each merchant has different rules and systems for:
  • 🔗 Resolving the correct product URL
  • 💰 Retrieving accurate pricing & availability
  • 🚚 Selecting shipping methods
  • 🧾 Calculating taxes
  • 🔒 Processing checkout securely
  • 📦 Handling order tracking and latency
Without Rye, every one of these steps requires custom code and brittle integrations.

​
The Rye Solution

With Rye’s Universal Checkout API, you only provide:
  • The product URL from any merchant
  • The buyer identity
Rye handles the rest:
  • ✅ Validate product data
  • ✅ Manage shipping and tax calculations
  • ✅ Submit the order to the merchant
  • ✅ Relay order status back to you
This lets you focus on building the user experience, while we handle the messy ecommerce details.

Your First API Call

Here’s how simple it is to create a Checkout Intent: 
curl --request POST \
  --url https://staging.api.rye.com/api/v1/checkout-intents \
  --header "Authorization: Basic $RYE_API_KEY" \
  --header 'Content-Type: application/json' \
  --data '{
    "productUrl": "https://flybyjing.com/collections/shop/products/sichuan-chili-crisp",
    "buyer": {
      "postalCode": "10001",
      "country": "US",
      "province": "NY",
      "city": "New York",
      "address2": "Apt 1",
      "address1": "123 Main St",
      "phone": "212-333-2121",
      "email": "john.doe@example.com",
      "lastName": "Doe",
      "firstName": "John"
    },
    "quantity": "1"
  }'
Rye abstracts all the complexity. You send a URL and buyer info, we handle shipping, taxes, and order placement.
