Broker that takes SOAP calls or web based API

Is there a broker that will accept trades and stream quotes through the web?

I have created my own EA in PHP / MySQL and I want to let that run on a web server, and just signal the broker to start a trade through a web call, kinda like how api's work with ebay / yahoo, you can just request a specific "page" and the broker accepts the instructions.

I need it to have low minimums, because I would like to start this on an account with around $250, mainly incase my program goes crazy and loses all my money.

if you are not willing to pay or to trade a substantial account then I suspect your options are limited for APIs... there are some info on APIs in previous threads on this site.

i think forex.com (gaincapital) has what you need
