Just wondering what kind of free finance API's are out there. I'm looking for something where I can specify the index and get a list of all the companies, by ticker symbol, that are included in that index.
Currently I'm only interested in NYSE-listed company stocks. I'd really appreciate any suggestions on API's or methods.
I just came across this service. You can download complete listings for the popular exchanges.

You must register (free plan) to download.
Thanks for the link driis but i'm not sure you can get complete listings. I looked at that before and it seems that it is just for managing your Google Finance portfolio.
