API

The entire dataset is open. These are plain files. You need neither a sign-up nor a key, and there is no rate limit. If you want to build a Discord bot, a spreadsheet or your own tool with it, go ahead.

Condition

One: name the source. The game data itself comes from the game client, from rAthena (GPL-3.0) and from community contributions. Please pass that along.

Where these numbers come from

Three sources: the game client, the open rAthena collection and the community. rAthena is the framework but carries renewal data — drops, element, race and size match reliably, health points and experience differ in Zero. Where the client states its own numbers, those apply. Every value is labelled individually.

If you reuse the data, keep that in mind: health and experience values are not Zero-verified.
