Vaultoro

A ruby API client for vaultoro.com, a global bitcoin and physical gold exchange that runs 24 hours a day, every day of the year. Vaultoro facilitates the purchase of real 99.9% pure gold using bitcoin. Vaultoro gold is stored in a high security vaulting facility operated by ProAurum AG in Switzerland, the largest precious metals dealer in Europe. All gold is 100% allocated, reserved and secured under your name as your property and all holdings are audited by one of the largest auditing firms in the world - BDO International. In addition every gram of gold is professionally insured against physical loss for full replacement value. All transactions are instantly settled, and publicly audit-able via the Glass Books Protocol.

This ruby gem is currently being used by Exavest to provide an additional portfolio facet. You can be assured the API will remain consistent and stable should you choose to utilize it yourself.

The Vaultoro ruby gem implements the full API provided by Vaultoro. Please note the Vaultoro API is still in beta and is subject to change without notice, consequently this gem may also break without notice. Please report any issues immediately and I will endeavor to patch the gem and issue a release.

To use the gem to issue buy, sell or cancel orders, query your account balance, open orders or closed trades, and withdraw bitcoin; you will need a Vaultoro account and a set of API keys.

Installation

To install add the following line to your Gemfile:

gem 'vaultoro'

And run bundle install.

Alternatively, you can install it from the terminal:

gem install vaultoro

Dependencies

The Vaultoro ruby gem has the following runtime dependencies:

Virtus ~> 1.0.3

Compatibility

Developed with MRI 2.4, however the .gemspec only specifies MRI 2.2. It may work with other flavors, but it hasn't been tested. Please let us know if you encounter any issues.

Usage

Prerequisites

The Vaultoro ruby gem requires an API key and API secret to use the Trading API. By default the library will look for your API key and secret in the environment variables VAULTORO_API_KEY and VAULTORO_API_SECRET.

Environments

The Vaultoro ruby gem supports multiple environments. These environments don't have to match your application's environments. By default the environments provided by the client are :production, :test and :development. The default environment is :production and the credentials for this environment are read from ENV variables.

If you'd like to override this behavior and provide the API key and/or secret directly to the client, setup a configuration initializer as shown below:

Vaultoro.configure do |config|
  config.credentials[:production][:api_key] = "B04B4E74C57C37DE4886"
  config.credentials[:production][:api_secret] = "s3kr3t"
  config.credentials[:production][:api_uri] = "https://api.vaultoro.com"
  config.credentials[:production][:api_version] = 1

  config.credentials[:test][:api_key] = "testapi"
  config.credentials[:test][:api_secret] = "testsecret"
  config.credentials[:test][:api_uri] = "https://api.vaultoro.com"
  config.credentials[:test][:api_version] = 1

  config.credentials[:development][:api_key] = "testapi"
  config.credentials[:development][:api_secret] = "testsecret"
  config.credentials[:development][:api_uri] = "https://api.vaultoro.com"
  config.credentials[:development][:api_version] = 1
end

Or pass the values directly to the attributes on the Vaultoro namespace:

# Set the environment to development:
Vaultoro.environment = :development

# The set the credentials:
Vaultoro.api_key = "B04B4E74C57C37DE4886"
Vaultoro.api_secret = "s3kr3t"
Vaultoro.api_uri = "https://api.vaultoro.com"
Vaultoro.api_version = 1

The Vaultoro ruby gem provides flexibility by allowing you to use whatever credentials you want, in whatever environment you want. You can, for instance, add a :staging environment if you want:

Vaultoro.credentials[:staging][:api_key] = "44CD64EEEFFF887755560B"
Vaultoro.credentials[:staging][:api_secret] = "another_secret"
Vaultoro.credentials[:staging][:api_uri] = "https://api.vaultoro.com"
Vaultoro.credentials[:staging][:api_version] = 1

You can query the current list of environments:

Vaultoro.environments #=> [:production, :test, :development, :staging]

And the currently selected environment:

Vaultoro.environment #=> :development

The current environment operates independently of any other framework environment, e.g. Rails.env or Rack.env. You can of course manipulate them to synchronize manually.

Tests are yet to be written, hence the pre version number. Since the next Vaultoro API is currently in discussion and I've been invited to discuss the new API, I decided to hold off on writing tests until I know where this API is heading.
