Do you have to pay for Carl bot?

Hello there, I was wondering about something related to Carl bot. I've heard a lot about its features and capabilities, but I'm still a bit unclear on one aspect - do you actually have to pay for Carl bot? I understand that some bots and services in the cryptocurrency and finance space can be quite costly, so I just wanted to get a clear understanding of whether Carl bot falls into that category or if it's available for free. Any clarification you can provide would be greatly appreciated.
