user41385: If I am using the API of bitcore.io and create transactions, how much transaction fees are taken by Bitcore?
I couldn't find any description in their documentation.

user21052: Bitcore is open source software provided at no charge, so there is no fee you have to pay to the BitCore software authors.
When creating a Bitcoin transaction, it is highly recommend that you pay a fee to Bitcoin miners to encourage them to include your transaction in a block.  How much fee you pay is optional, and there are a number of fee estimation services that will recommend a fee for you.  See also other questions on Bitcoin StackExchange for more information about transaction fees in general.
