## Usage

### Install

```bash
$ npm install --save btce-deal
```

### Init
BTC-E Deal provides separate objects for access to the Public and Trade API.

```javascript
var BTCE = require('btce-deal');

var btcePublic = new BTCE.Public(),
    btceTrade = new BTCE.Trade('YOUR-KEY', 'YOUR-SECRET');
```

Setting alternative domain
```javascript
var host = 'new domain';

var btcePublic = new BTCE.Public(host),
    btceTrade = new BTCE.Trade('YOUR-KEY', 'YOUR-SECRET', host);
```

All methods return a `Promise` object ([bluebird](https://github.com/petkaantonov/bluebird) implementation).
```javascript
btcePublic.getInfo()
    .then(function (data) {
        // success handling
    })
    .catch(function (data) {
        // error handling
    });

btceTrade.getInfo()
    .then(callback)
    .catch(callback);
```
