    description <<-MD
      The QpxExpressAgent will tell you the minimum airline prices between a pair of cities, and within a certain period of time.

      Follow their introduction documentation here (https://developers.google.com/qpx-express/v1/prereqs#get-a-google-account) to retrieve an api key.
      After you get to the google chrome console and enabled qpx express api, you can choose `api key` credential to be created.
      For round trips please provide a `return_date`.
