eth_estimateGas

Returns an estimate of how much gas will be needed for the transaction to complete. When estimating gas, the transaction will not be automatically added to the network. This cannot be used as a hard indicator, as fluctuations on gas prices can occur very quickly, making estimates inaccurate after just a few seconds.
