Finnish Parliament votings API

Parliament voting data visualized and published as a RESTful API.

Results of the votings by the Finnish Parliament are available from the Parliament website, but they are difficult to find and read. It is especially tedious to find out what a particular parliament member has voted, because the results are divided accross hunderds of pages. Linking to individual voting is also impossible, because the website uses temporary addresses which expire after few days.

To make things easier, I built an unofficial RESTful API, which publishes the voting data in machine-readable XML-format. This API can be used as a data-source for new applications (examples below).

API Manual

Data is fetched from the Parliament website by semi-automatic screen scraper. The API currently contains data from about 500 votings. Data is not checked thoroughly, so it can contain errors (but none found so far).


Identifiers for the votings are formatted like a{votingnumber}_{sessionnumber}-{year}. Other data comes from the Parliament website as is in unmodified form.

List of all votings

Data about a voting{äänestyksen tunniste}


Data about a parliament member{sukunimi etunimi}

Examples: and

Spaces and special characters are replaced with corresponding thee-character codes.

Votings with a keyword{keyword}


This returns data from those votings (no more than 20), which headers contain the keyword. Spaces and special characters are replaced with corresponding thee-character codes.


These are the visualizations and tools I have built on top of the API (In Finnish only):

  1. Votings
    1. Each voting has a page, which shows how members and parties have voted. Top-right box shows the total result by parties with one glimpse.
      Example: changes to the copyright law, the so called ”Lex Karpela”
  2. Parliament members
    1. Each member has a page, which lists all her/his votings.
      Example: Jyrki Kasvi
  3. Voting analyzing machine lets you compare your opinions to those of the parliament members. The machine finds the best and worst matching parliament members according to your answers.

Key to colors:

  • green = yes
  • red = no
  • blue = empty vote
  • gray = not present

New votings added to the API are displayed as Twitter and Facebook feeds.
