Getting a value from JSON, Node.js

I am having trouble with getting a value from inside of a JSON file, which has been retrieved from the Steam API (http://ift.tt/16KNZkA).

The problem occurs when I attempt to print the data, the Node.js file code is below:

var data = JSON.parse(body); // Stores the JSON data which has been retrieved
console.log(data.result.toString(350462890).market_hash_name); // Attempts to grab the value of the market_hash_name from the JSON data and display it to screen

I get the following response: "undefined".

JSON data used below:

        },
        "classid": "350462890"
    },
    "success": true
}

}

So does anyone have any idea how I can return the market_hash_name? also please take note, I am fairly new to using Node.js.
