Is Covalent API free?
Excuse me, could you please clarify if the Covalent API is available for free? I'm interested in using it for my cryptocurrency projects, but I want to ensure there are no hidden costs associated with its utilization. It would be great if you could elaborate on the pricing structure, if any, or if there are any limitations for free users. Additionally, if there are premium features available, I'd like to know more about them and their respective pricing. Thank you in advance for your assistance.
