Leveraging APIs

Is anyone leveraging APIs to populate live data into their courseware using the "Execute JavaScript" action?

Like weather (http://weathersource.com/weather-api) or Stocks (http://sourceforge.net/projects/yahoofinanceapi/)

I want to use this data to determine variables in my courseware so it is different everyday. An example could be for managing a budget. The learner must manage the project budget based on the current stock market. So when the Nasdaq is down by X, now the learner must accommodate the budget based on this reduction.

Learner has to complete a crisis management process based on the weather in their area. Learner puts in a zip code and the courses' variables adjust based on the current weather conditions for their area.
