Provides a Ruby library to the complete Bitcoin JSON-RPC API. Implements all methods listed at en.bitcoin.it/wiki/Original_Bitcoin_client/API_Calls_list. Also supports customizing the host and port number to connect to.

Installation¶ ↑

On Ruby 1.9, you can just install the gem and start using it. On 1.8, the ‘json’ gem is also required, so you’ll need to install that first:

gem install json

Or, if you’re using Bundler (and you should be), just add it to the Gemfile:

gem 'json', '~> 1.5.3'

Usage¶ ↑

As with most Ruby gems, you first need to require the library into your project:

require 'bitcoin'

After doing this, the simplest possible usage looks like this:

Bitcoin('username', 'password').balance
# => 0.001

Or, if you prefer a somewhat more explicit representation, the following code performs the exact same task:

client = Bitcoin::Client.new('username', 'password')
client.balance
# => 0.001

The third and final way to use the library is by taking advantage of a simple DSL:

include Bitcoin

# set up credentials
username 'username'
password 'password'

balance
# => 0.001

accounts
# => {"account" => 0.001}

The RPC method names available to you are exactly the same as those listed on the Bitcoin wiki (again, that’s en.bitcoin.it/wiki/Original_Bitcoin_client/API_Calls_list). Some aliases have been added to make them more “ruby-ish,” but none of the original names have been changed.

Host, Port and SSL¶ ↑

Here are several examples of how you can change the host information:

Bitcoin('username', 'password', :host => 'example.com', :port => 38332, :ssl => true)

client = Bitcoin::Client.new('username', 'password', :host => 'example.com')
client.port = 38332
client.ssl = true
client.ssl?
# => true

include Bitcoin
host 'example.com'
port 38332
ssl?
# => false
ssl true
ssl?
# => true

You should see the Bitcoin::Client class documentation if you’d like to see the other options and methods that are made available.

Donations¶ ↑

If you found this library useful and feel inclined to compensate me for my trouble, I’m certainly not going to turn you down!
