Is Gemini API still free?

I'm curious to know, is the Gemini API still offered for free? As a frequent user of cryptocurrency exchanges and their APIs, I've noticed that some platforms have started to charge for access to their API services. Does Gemini follow this trend, or do they continue to provide their API at no cost to developers and traders alike? I'm interested in integrating Gemini's API into my own projects and would like to clarify the current pricing structure before proceeding.
