How to get S&P 500 current price by using Yahoo API

Question

Is there way to get S&P 500 current price by using Yahoo API?

I've read through this page, but could not find out how to do it. http://www.gummy-stuff.org/Yahoo-data.htm

I also tried to use YQL to get data, but it seems like YQL doesn't provide finance API currently.
