LibWowAPI (formerly LibWowArmory) is a library for the .NET framework that interfaces with the Blizzard World of Warcraft API. The Blizzard World of Warcraft API ( is an online API that interfaces with World of Warcraft.

Be sure to check out my other WoW-related projects:


  • Json.Net 4.0r2 - A free JSON library for .NET. See the Getting Started guide for more details.


See the documentation for more information on how to use LibWowAPI in your .NET application.

Version History

1.0 - 8/27/2011

  • Implemented gzip compression.
  • Added battlegroup listing and auction hall classes.
  • Completed the item lookup class.
  • Added battlegroup field to the realm lookup class.
  • Added talents field to the pet class of the character class.
  • Fixed a bug with URLs that contain pound signs (#) that aren't part of hashes and ampersands (&) that aren't part of querystrings. Yes, this was needed.
  • Standardized the way the class constructors work so that a constructor with no arguments requires you to call the Load() function while a constructor with arguments does not.
  • Help documentation available.

0.5 beta - 8/18/2011

  • Project name change from LibWowArmory to LibWowAPI.

  • Added pvp and quests fields to the character profile.
  • Added character achievements, guild achievements, quests, and arena ladder classes.
  • Better item lookup support.
  • Some properties are now shared/static across the library in order to allow for cleaner code. These properties should be set at startup time, or in the application start event for ASP.NET.
  • Changed LastModified header to IfModifiedSince header.
  • The library now sends the X-Library and X-LibraryURL headers identifying itself to Blizzard as LibWowAPI and linking to this project. You can optionally send the X-Application and X-ApplicationURL headers - set via the shared/static properties Application and ApplicationURL - to identify your application.

The source code of LibWowAPI comes with the LibWowAPIDemo application. This console application is designed to provide potential developers with a working example of how to use LibWowAPI in their own applications. It's a great way to learn how to use the library.

Special Thanks

  • Lukan Schwigtenberg contributed the first working copy of the now-removed ItemTooltip class.
