Api trading platform

Good day everybody, could anybody please suggest good online trading platforms that offer server to server API with no limit data feed nationwide(US Markets). Thank you.

Let me guess, you're building your own algorithms on your server and want to draw the data from a broker server next to NYSE or Nasdaq and order flow back through the broker server accordingly?

SURPRISE!!! Most brokers actually offer API's to developers these days. Even retail Etrade & Ameritrade. You just have to know who to ask. A simple Google search for "Etrade API" or "Ameritrade API" gets you started. You're smart, you'll find what you are looking for from there, I'm sure. Good Luck with that algo!
