Can't get withdrawal fees of any exchange

I am working on a code that analyzes the markets of 8 different exchanges. Under no circumstances am I able to obtain withdrawal fees for a particular market. While using the proposed function on the documentation for withdrawal fees:

exchange.currencies['ETH']['fee']

I give an error for all 8 exchanges:

currency = exchange.currencies['ETH']['fee']
KeyError: 'fee'

Is there any way to get these fees?

@Epikem @radadan there are no withdrawal fees for markets, rather there are withdrawal fees for currencies, and these fees vary depending on the network, some exchanges have a fetchTransactionFee(code, params = {}) or fetchTransactionFees(codes, params = {}) methods, (eg: kucoin, bitmart, bibox)which return information about withdrawal and deposit fees for specific currencies if available. However the unification of these methods is work in progress and is not present in most exchanges, hope this helps. On some exchanges (for example binance and huobi) you can also find information about withdrawal fees by network in the currency object, however this information is also not always available.

import ccxt
exchange_id = 'kucoin'
exchange = getattr (ccxt, exchange_id) ()
exchange.load_markets ()
transaction_fees = exchange.fetchTransactionFee('USDT')

Returns: { info: { code: '200000', data: { currency: 'USDT', limitBTCAmount: '1.00000000', usedBTCAmount: '0.00000000', remainAmount: '30522.368535', availableAmount: '0.000000', withdrawMinFee: '25', innerWithdrawMinFee: '0', withdrawMinSize: '50', isWithdrawEnabled: true, precision: 6, chain: 'ERC20' } }, withdraw: { USDT: 25 }, deposit: {} }

import ccxt
exchange_id = 'huobi'
exchange = getattr (ccxt, exchange_id) ()
exchange.load_markets ()
# if available contains
currency = exchange.currency ('BTC')
# if available contains withdrawal information by chain
networks = currency['networks'] 

The networks object will contain information about withdrawal fees for specific networks (if available), otherwise the currency object may contain information about fees.
