请问币币账户向合约账户转账能通过API实现吗

多谢梦总！

只要交易所提供有 转币 提币 等API 接口 ， 都可以用 exchange.IO 直接调用这些接口。
在数字货币交易类库 模板里有相关 代码 ，可以参看：

            
            
            
$.withdraw = function(e, currency, address, amount, fee, password) {
    var withdraw_id = null;
    var ret = null;
    currency = currency.toLowerCase()
    switch (e.GetName()) {
        case "OKCoin_EN":
            ret = e.IO("api", "POST", "/api/v1/withdraw.do", "symbol="+currency.toLowerCase()+"_usd&chargefee=" + fee + "&trade_pwd=" + password + "&withdraw_address=" + address + "&withdraw_amount=" + amount);
            if (ret && typeof(ret.withdraw_id) !== 'undefined') {
                withdraw_id = ret.withdraw_id;
            } else {
                var err = GetLastError();
                if (err && err.indexOf('10031') !== -1) {
                    Log("OKCoin_EN 需6个网络确认后方能提现");
                }
            }
            break;
