API Documentation
Our API allows you to programmability interact with our exchange system. This documentation is for our REST API.
We also have a Websocket API available for realtime trade and orderbook data.
The API is divided into two sections
- Public API: Which allows anyone to lookup market data about the exchange; such as rates, order book volume, etc...
- Private API: Which requires users to have an account with us; the private API allows users to interact with their account; such look balance inquiry, place orders, canceling orders, viewing history, etc...
Public API
To use the public API no authentication is required; simply access any of the public API URLs and JSON encode data will be returned.

Private API
To use the private API you must generate an API Key in your account area. Each API key generated will have an "API Key" and an "API Secret".
Every query to the private API must include the following POSTed fields:
key- API Keynonce- Noncesignature- Signaturetwofa- 2Factor Auth. Code *
API Key
The API Key in found in the "API Key" column when you generate your API keys.
Nonce
This is an integer value that must increase with every API call you make, for example if your first API call uses nonce=1 then the next API call must use a nonce of 2 or greater
A common practice is to use unix time for that parameter.
Signature
A SHA-256 hash of the following data api_key + nonce + api_secret
A PHP example:
$signature = hash('sha256',$api_key.$nonce.$api_secret);
2Factor Auth. Code
Only required if you have enabled two factor authentication on the API key
