ytj_client

A really small gem to fetch and parse data from the Finnish Patent and Registration Office's (PRH) YTJ-tiedot (business information system) API at http://avoindata.prh.fi/ytj.html

Makes the API call for you and parses the relevant (in my opinion) information to a convenient format (Ruby hash).

Add this line to your application's Gemfile:

gem 'ytj_client', '~> 0.3'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install ytj_client

Fetch company details with a business_id:

require 'ytj_client'
YtjClient.fetch_company('2331972-7')
# => #Hash {
#           :business_id => "2331972-7",
#                  :name => "Verso Food Oy",
#     :registration_date => "2010-04-20",
#          :company_form => "OY",
#                :phones => {
#         :mobile_phone => "+358400770697"
#     },
#               :website => "www.versofood.fi",
#             :addresses => {
#         :visiting_address => "Loisteputki 4, 00750, HELSINKI",
#           :postal_address => "Loisteputki 4, 00750, HELSINKI"
#     }
# }

Fetch companies between two dates.

require 'ytj_client'
companies = YtjClient.fetch_companies(start_date: '2017-05-01',
                                      end_date: '2017-05-31',
                                      options: { mode: :array })
companies.each { |company| p company.inspect }

Fetch all companies that are available in the TR API since the year 1896. This is well over 300 000 companies so it will take a while. Saves the results in a companies.csv file.

require 'ytj_client'
YtjClient.fetch_all_companies
