Oraclize Example App

That's a sample application to demonstrate working with Oraclize in Ethereum Studio.

Clone the project to your workspace.
Select the project and start a sandbox. It will use Oraclize sandbox plugin with the following params (see ethereum.json):

"plugins": {
  "oraclize": {
    "networkID": 161,
    "loadRealData": true
  }
},

Open a dialog of contract Contract and call update() with value 100000000000000000 in advanced parameters.

You will see requests and response in Oraclize Panel and contract logs in Ethereum Console.
