Is Coinbase one a monthly subscription?

Excuse me, could you clarify something regarding Coinbase? I've been hearing about this cryptocurrency platform and its services, but I'm a bit unclear on one aspect. Specifically, does Coinbase operate on a monthly subscription basis? Is there a recurring fee that users need to pay each month to maintain their accounts and access the various trading and wallet services offered? I'd appreciate any clarification you could provide as I'm considering signing up but want to ensure I have a full understanding of the financial implications upfront.
