Frequently Asked Questions

Q. How do you access (and provide) all of this data?
We've developed an automated way of processing, optimizing, and delivering Maplestory assets without extracting each individually.

This allows us to serve real-time rendering APIs for every region, with no hassle on the developer's end.

Q. What can't I do with these APIs?
We ask that you are mindful of Nexon America's Terms of Service, by only using our APIs for non-commercial reasons.

You are not allowed to profit in any way from the assets provided by our APIs, and must provide credit to Nexon where and when appropriate (see our footer for an example).

Q. Where can I report something broken?
Let us know on Discord or send an email to [email protected].
