This is my second extension and it uses the Wolfram|Alpha API. Wolfram|Alpha is a computational knowledge engine that can answer requests. You can get a free API Key for up to 2,000 non-commercial API calls per month. You need to get an API Key here: https://products.wolframalpha.com/api/. Then set AppID to your appID and get started!
