    Hello I am building a model in C# and need a source for quotes. Does Google finance offer an api? Or can I automate this with some other service for free? I am not interested in free trials, only in perma free systems. How do you get your stock/options quotes for your models? Anyone have code samples?

    I know there is a program called RTQ downloader from
    It appears that their data comes from Yahoo's API.

    You might look into QuoteTracker, they have an API for quotes. They are free, if you can handle ads. Cheap if you cant.
