SejmNet is a C# production-ready client library for the official API of the Parliament of the Republic of Poland (Sejm) available at

Supported platforms

Currently, the package supports .NET 8 or later.


To get access to the API, simply create a new instance of SejmNet.SejmClient and call an appropriate method.

using SejmNet;
using SejmNet.Models;

SejmClient client = new();

// Returns information about all clubs in the 10th term of the parliament.
Club[] clubs = client.GetClubs(10);

// Returns information about a parliament member with ID 148 in the 10th term of the parliament.
ParliamentMember? member = client.GetMember(10, 148);

Known issues

  • ISejmClient.GetPrints() - /sejm/term{term}/prints - tends to have EXTREMALY low performance (like, requests can last for literal minutes), using this method should be avoided if possible.

  • ISejmClient.GetPrints() - /sejm/term{term}/prints - the 'sort_by' parameter is not supported by the library, as it does not seem to work.

  • IEliSejmClient - /eli/changes/acts - this action is not implemented, it seems like it doesn't work properly.
