Topic: Introducing api.pvpgn.pro
New https://api.pvpgn.pro service is available for public. And nothing prevents from launching own hosted instance
There are only two methods now, and I hope they will be increased in the future. You can send pull requests with new features which related to pvpgn and can be useful for others
First app I made using the API is Diablo 2 Character Editor. This is only an example and it does not support full character editing features like moving items in inventory (but it's allowed by API).
Sure its possible to use the API for automation such things for very different purposes that you can imagine.
API method /d2char can be used as a better replacement of old d2smanager.harpywar.com
