Is ZebPay free?

Excuse me, could you please clarify if ZebPay is a free service or does it come with any costs associated with its usage? I'm interested in exploring the platform but would like to know if there are any upfront or ongoing fees that I should be aware of. It would be great if you could provide me with a comprehensive overview of the pricing structure, if any, before I proceed. Thank you in advance for your assistance.
