Small fast (and complete) Java API for the Cryptsy crypto-currency exchange with minimal dependencies. The only external library needed to use this API is the Google Gson Library.
Note: While the API is complete and functional in its current state, I am refining the naming conventions for the API and adding documentation. This may require small but critical changes to your code if you upgrade to future versions.
Add the file Cryptsy.java to your project and include the Gson jar as a reference. Thats all thats needed. The unit tests for this library use a properties file for saving the API keys but thats not a requirement. The use of the properties file is only a requirement of the unit tests and not the API itself.
Create a Cryptsy API object using the following code:
cryptsy = new Cryptsy();
cryptsy.setAuthKeys("<api_key>", "<api_secret>");After this, using the API is as simple as calling the appropriate method off of your cryptsy object. It is useful to look at the Cryptsy_Test.java source code since the unit tests in this file contain sample code for all of the APIs. I'll be adding a complete javadoc in the near future.
Obtain account info including account balances and amounts on hold due to open orders:
InfoReturn info = cryptsy.getInfo();
System.out.println(info);
for (String currency : info.balances_available.keySet()) {
double val = info.balances_available.get(currency);
if (val > 0)
System.out.println(" Available " + currency + "=" + val);
}
for (String currency : info.balances_hold.keySet()) {
double val = info.balances_hold.get(currency);
if (val > 0)
System.out.println(" Hold " + currency + "=" + val);
}Get the account transactions.
Transaction[] transactions = cryptsy.getMyTransactions() ;
for(Transaction t:transactions) {
System.out.println(t) ;
}Returns all the orders (order book) for a single currency market.
MarketOrderReturn mo = cryptsy.getMarketOrders(Markets.WDC_BTC) ;
System.out.println("Sell Orders") ;
for(MarketSellOrder so:mo.sellorders) {
System.out.println(so) ;
}
System.out.println("Buy Orders") ;
for(MarketBuyOrder bo:mo.buyorders) {
System.out.println(bo) ;
