eth_estimateGas | Alchemy Docs

Generates and returns an estimate of how much gas is necessary to allow the transaction to complete.

linea_estimateGas uses the same inputs as the standard eth_estimateGas, but returns the recommended gas limit, the base fee per gas, and the priority fee per gas. We recommend using linea_estimateGas for more accurate results.
