# Whisk Sandbox When you [create a new account](https://docs.whisk.com/master/guides/creating-an-account), you'll receive a key for our Whisk API sandbox called the Test Kitchen. The Test Kitchen API is similar to the same ones you'd find in production. This sandbox is designed to help get you started with all of the API's features. However, it's important to know that there are some limitations imposed on Test Kitchen. Here are the key differences to be aware of between the sandbox and production APIs: ### API Host **Test Kitchen:** `testkitchen.whisk.com` **Production:** `graph.whisk.com` ### Recipe Search & Recipe Feed **Test Kitchen:** A small subset of recipes are available through the search and feed specifically validating that everything is wired up correctly. **Production:** Your recipe visibility depends on your Whisk agreement. You can discuss the details with your Whisk contact. ### Retailers **Test Kitchen retailers:** Walmart (US, all zip codes) and Tesco (GB) **Production retailers:** ### List Transfer (aka: Shopping list mobile) All successful list transfers return the same transfer URL. ### Call frequency **Test Kitchen:** 10 calls per second, 200 calls per day **Production:** unlimited calls per second, calls per month defined by your contract ### Example `curl "https://testkitchen.whisk.com/v1/search?type=recipe" \`\ `-H 'Authorization: Token ’`
