I need a currency converter-free API key. Otherwise, my currencies are not working.

API key is Required

Hello,

I've set up my currency types in Travelo Options and also in the wocomerce Multi Currencies  (Attached)

Is there anything i need to do so the conversion for the currencies will work ? Right now when I change currency from my defult (USD) the prices not appearing

Do I need to make another currency conversion connection to any IFC or API so it will work properly ?

Thanks
