Tradier API

For Developers, by Developers.


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. Simply POST parameters, just like any other API call.

OAuth 2.0

The new OAuth specification makes it easy to give users access to your application. Plus it's a piece of cake to integrate with web, mobile or desktop platforms.

Streaming Data

Realtime data APIs at your fingertips, from streaming data and live customer events all available through a standard HTTP-based API.

"How-to" Docs

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.
