Overview

The getFeeForMessage method is used to estimate the transaction fee for a given message. This is very useful when you are preparing to send a transaction and you want to estimate the transaction cost. This can be used in situations where you need to validate whether a user has enough funds to cover the transaction fee or to provide an estimate of the cost to the user.

• message(string, required): Base-64 encoded Message for which the fee should be estimated.
  • Example: "AQABAgIAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAEBAQAA"
• options (object, optional): Configuration object containing the following fields:
  • commitment (string, optional): Specifies the confirmation level of data to be fetched.
    • Values: finalized confirmed processed
  • minContextSlot (number, optional): The minimum slot that the request can be evaluated at
    • Example: 1000

Return Object

The result will be a JSON object with value equal to Fee corresponding to the message at the specified blockhash
