Important
Use the trailing slash on every request or your API Auth will fail. The URL listed is the exact URL needed to access Novaexchange by API.
The binary signature of the request has to be a base64 encoded string before sent to the server.
Nonce is enforced on private API calls in APIv2 and has to be included in url before signing it with your secret key.
List markets summary, including cached tickerdata (Limited to 1 request per minute).
