Irish Company search #API example in C#

logo-Companies-Registration-OfficeLike the UK’s companies house, you can access basic information about Irish companies using an API that is free to use (mostly), and quite easy to implement.

I say mostly, because unlike the UK version, they charge €2.50 for document downloads.

Here’s the code example (without my credentials) in c#

var strUrl = “https://services.cro.ie/cws/companies?company_num=389820&htmlEnc=1”;

string userName = “** An email address **”;
string password = “**A GUID**”;
WebClient client = new WebClient();
string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(userName + “:” + password));
client.Headers[HttpRequestHeader.Authorization] = string.Format(“Basic {0}”, credentials);
client.Headers[HttpRequestHeader.Accept] = “application/json”;
string strJson = “”;
strJson = client.DownloadString(strUrl);
catch (WebException exception)

if (exception.Response != null)
var responseStream = exception.Response.GetResponseStream();

if (responseStream != null)
using (var reader = new StreamReader(responseStream))
strJson = reader.ReadToEnd();
