We provide both a Websocket API and Representational State Transfer (REST) API which you can easily access through HTTPS requests.
There are two types of API methods: public methods and private methods. Anyone can use the public methods, for instance to retrieve market data. All you need to do is to paste the HTTPS request in your browser or write a piece of code that sends these requests automatically.
To access the private methods, you need to be a verified user and generate your personal set of API keys. Under settings, navigate to the API Keys section:
These keys are used to encrypt your communication with the API. You can then programmatically send orders to the market, cancel orders or see your trades history.
The API is described in more detail here.
