People think mistakenly that gas price for normal transactions in ETH is the same for contracts (including transferring tokens), in fact, each contract has its own gas price. That's why we have created a new endpoint for retrieving the gas price per contract (token).

The new endpoint will return: slow, standard, and fast values, all in Gwei.
