You might be familiar with Nadeo's "stats server": a set of php scripts that you can call to retrieve various game information ; it is used by community websites such as tm-ladder. Today, we are releasing a new version of the stats server along with an open source SDK for PHP!
We'll referer to our new API as TrackMania Web Services, and the new URL is ws.trackmania.com. You can very easilly do a anonymous test call to the dummy service (try it with your browser or any HTTP client):
We also decided to open-source the PHP library to interact with the API. You will find a small tutorial and download links in this topic: http://forum.maniaplanet.com/viewtopic.php?f=206&t=1207
A .NET SDK is also available. Check this topic for more information: http://forum.maniaplanet.com/viewtopic.php?f=206&t=1266
If you don't use PHP but you want to use the API directly you're also welcome to hop in. We'll provide information about how the API works (but it's pretty simple anyway).
