How do I get my Nekovia code?

Excuse me, could you please elaborate on how one might acquire the Nekovia code? I'm quite interested in the process and would appreciate any guidance you could offer. Is there a specific website or platform where I should go to request or purchase the code? Are there any prerequisites or steps I need to take before I can obtain it? Additionally, is there a fee associated with acquiring the Nekovia code, and if so, what is the typical cost? Thank you for your time and assistance.
