A full-range of services in a scalable, secure and easy-to-use REST-based API
for businesses and developers. It’s unlike anything you’ve seen before.
Paper trading and market data help you start building your applications with no risk to you.
We make it simple to access streaming market data events from our robust HTTP-based API.
Signup and you will get immediate access to the APIs.
No gotchas. No fees. No, really.
All calls follow REST concepts and can be made with any language that supports a standard HTTP client.
We made the trading API as easy as possible. No specialized formats or message types. Simple POST parameters, just like any other API call.
The new OAuth specification makes it easy to give users access to your application and quickly integrate it with web, mobile or desktop platforms.
Realtime data APIs at your fingertips, from streaming data to live customer events, all available through a standard HTTP-based API.
All the documentation is written to get you going quickly. You don’t need to know the right call, just what you want to do: “Place a trade” or “Create a watchlist.”
We’ve created example cURL requests for each API, showing you exactly how to create the request, send it to the API, and get a response.
