Can I charge for my services based on coingecko API?

Can I use the coingecko API to determine pricing for my cryptocurrency-related services? I understand that the API provides real-time market data, but is it permissible to base my service fees on this information? Additionally, are there any legal or ethical considerations I should be aware of before implementing such a pricing strategy? I'd like to ensure that I'm adhering to best practices and respecting the terms of use for the coingecko API.
