The Cointrader.net REST API offers access to Cointrader.net's bitcoin exchange services. Make public calls to the API with HTTP GET, and authenticated calls with POST. All requests return in JSON and authentication is done via a private/public key combination that utilizes HMAC-SHA256. Use Cointrader.net to buy/sell bitcoin with Canadian or US dollars, return information on trades and market data, manage your account, or deposit/withdraw bitcoin orders. See the API documentation for information on getting started and an API sandbox environment.
