Fee estimation is integrated within the Transaction API and is not a standalone endpoint. When you send a transaction, the fee is automatically deducted from the sender's wallet.

How It Works?

It estimates the cost of sending a transaction, which can be either signed or unsigned. If unsigned, the estimation assumes the size of a single signature. The estimation includes:

Bandwidth: The data size of the transaction.
Energy: The computational resources needed if it's a smart contract transaction.
Additional Fees: Any extra costs for specific contract types.
