Is the Gemini code free?

Excuse me, could you please clarify if the Gemini code is available free of charge? I've been hearing a lot about its advanced security features and I'm quite interested in incorporating it into my cryptocurrency exchange platform. However, I'm on a tight budget and would like to ensure that there are no hidden costs or subscription fees associated with using the Gemini code. Could you provide me with more information on its pricing structure and whether there are any alternatives available if the Gemini code does not come free of charge? Thank you in advance for your help.
