Usage

To use LichessNET in your project, you will have to include the LichessNET.API namespace:

Without Lichess Token

using LichessNET.API;
var client = new LichessAPIClient();

With Lichess Token

using LichessNET.API;
var client = new LichessApiClient(/* YOUR OPTIONAL LICHESS TOKEN */);
//If your token became invalid, the client will fall back to not using a token.

Code Snippets

Access games from Lichess

By Game ID:

  var game = await client.GetGameAsync("cFcjVWzn");

Download from the monthly database:

   var database = new DatabaseClient();
   await database.DownloadMonthlyDatabase(2015, 1, ChessVariant.Atomic, "2015-01", false);

You can find the Game ID of a game in the URL of the game.

Challenges

  bool accepted = await client.AcceptChallengeAsync("challengeId");
  bool declined = await client.DeclineChallengeAsync("challengeId");
