https://mtgox.com/apiAll of the API methods below have cached results, ticker, depth . . . have a 10 seconds cache . No need to poll more often, you wont have more results, you could just be blocked by the prolexic anti ddos features.
I need to get the prices for all currencies. To do this I would have to go to the ticker for each currency. Eg.
http://mtgox.com/api/0/data/ticker.php?Currency=USD
http://mtgox.com/api/0/data/ticker.php?Currency=AUD
http://mtgox.com/api/0/data/ticker.php?Currency=EUR
etc.
Will doing this get my server blocked from the DDOS protection?
