Ask HN: Any open source / free stock quote APIs available?

  Google finance, albeit the API isn't as developed as you might expect but most everything you need is there.

  You can use the Yahoo CSV file generator: http://ichart.finance.yahoo.com/table.csv?s=YHOO&a=00&b=1&c=2012&d=03&e=1&f=2012&g=d&ignore=.csv http://ichart.finance.yahoo.com/table.csv?s=YHOO&a=00&#3... This is an example for Yahoo quotes from Jan 1 2012 until April 1 2012. So exchange YHOO for the ticker you want. And then: a = start month (always dubble digit and 1 less then month number, so april is 03, dec is 11, etc) b = start day (no 0 in front if < 10) c = start year d = end month (always dubble digit and 1 less then month number, so april is 03, dec is 11, etc) e = end day (no 0 in front if < 10) f = end year

    Thanks for the tip, and the primer Was hoping for something a little more directly consumable, but a CSV isn't the worst thing in the world.
