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

Just curious

You can use the Yahoo CSV file generator: http://ichart.finance.yahoo.com/table.csv?s=YHOO&a=00...

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.

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

I'll check it out, thanks.
