    module Agents class GoogleFlightsAgent < Agent include FormConfigurable cannot_receive_events! default_schedule "every_12h" description <<-MD The GoogleFlightsAgent will tell you the minimum airline prices between a pair of cities. The api limit is 50 requests/day. Follow their 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 developer console, created a project, enabled qpx express api then you can choose `api key` credential to be created. The `origin` and `destination` options require an [airport code](http://www.expedia.com/daily/airports/AirportCodes.asp). All the default options must exist. For `infantInSeatCount`, `infantInLapCount`, `seniorCount`, and `childCount`, leave them to the default value of `0` if you do not need them. Make sure `date` and `return_date` is in this date format: `YYYY-MM-DAY`. You can choose one way tickets only by setting `roundtrip` to `false`. You can limit the number of `solutions` returned. The first solution will be the lowest priced ticket. MD event_description <<-MD The event payload will have objects that contains valuable data like this "carrier": [ { "code": "B6", "name": "Jetblue Airways Corporation" } ] "tripOption": [ "saleTotal": "USD49.10" "slice": [ ... ...
