API

[Forex Trader]

I see there are three API's available for download. Are any of these targeted for the client side or are all of them server side? I am not even sure if I am asking the right question here. I am interested in the client side API and developing my own stand-alone programs. Also, I know MQ does not publish the brokers who use or will be using MT3/4 (any brokers serving data using MT4 yet?) so, as a trader, how can I find a broker who is serving data using the MT4 platform?

Thanks in advance
