Gathering data on several stocks at once via API?

I'm looking to pull a snapshot of all nyse stocks or just a subset if I have to do it that way at once. It seems all stock api's I can find seem to require a symbol to call and can only check one price at time. Ideally I'd like to do one call and get a list of active stocks and their current prices back in one JSON that I can process and log for later analysis.
