Please note that the Crunchbase API v2.0 was shut down on May 31st, 2015, and as such this gem is no longer functional.

Add this line to your application's Gemfile:

gem 'crunchbase-api'

And then execute:

$ bundle

Or install it yourself as:

$ gem install crunchbase-api

You will need a Crunchbase API key. You can get one by signing up here.

Crunchbase.user_key = 'YOUR_API_KEY'

# Print acquisitions done by Facebook

  puts "#{acquisition.announced_on.to_s}: #{acquisition.name} (#{sum})"

Failed requests (such as the ones requesting non-existent entities) will throw Crunchbase::CrunchbaseException.

.list methods take an order argument. Valid options are Crunchbase::ORDER_CREATED_AT_DESC (default), Crunchbase::ORDER_CREATED_AT_ASC, Crunchbase::ORDER_UPDATED_AT_DESC and Crunchbase::ORDER_UPDATED_AT_ASC.

.list methods return an array of Relation objects, as do the relationship getters for most individual entities. These are summary objects returned by Crunchbase API, containing type and name of the target entity, along with timestamps. You can retrieve the "full" entity by calling .fetch method on the relation object.
