# Cryptopia

A (unofficial) Node.js API client for the [Cryptopia][cryptopia].

The client supports public (unauthenticated) calls to the [Cryptopia][cryptopia-api]. Private calls coming soon.

For private calls, the user secret is never exposed to other parts of the program or over the Web. The user key is sent as a header to the API, along with a signed request.

## Clone from GitHub

    git clone https://github.com/sigwo/node-cryptopia.git
    cd node-cryptopia
    npm install


## Require as a module

In your app, require the module:

    var Cryptopia = require('cryptopia');

If not installed via NPM, then provide the path to cryptopia.js

## Create an instance of the client

If only public API calls are needed, then no API key or secret is required:

    var cryptopia = new Cryptopia();

## Make API calls

All [Cryptopia API][cryptopia-api] methods are supported (with some name changes to avoid naming collisions). All methods require a callback function.

```
cryptopia.getcurrencies(function(data) {
  console.log(data);
});
```
Response:
```
