# getFeeForMessage

Returns epoch schedule information from this cluster's genesis config.

This method will use `30` [Compute Units](/nodeapi/about/billing).

***

## **Parameters**

* `message` string *<span style={{color: "red"}}>Required</span>.* The transaction message encoded as base64.
* `object` *optional.* Configuration object containing the following fields:
  * `commitment` string. The level of commitment required for the query. The options include:
    * `finalized` string.
      * The node will query the most recent block confirmed by the supermajority of the cluster as having reached maximum lockout, meaning the cluster has recognized this block as finalized.
    * `confirmed` string.
      * The node will query the most recent block that has been voted on by the supermajority of the cluster.
    * `processed` string.
      * The node will query its most recent block. Note that the block may not be complete.
  * `maxSupportedTransactionVersion` number
    * The maximum supported transaction version to return in responses. If the requested block contains a transaction with a higher version, an error will be returned. If this parameter is omitted, only legacy transactions will be returned, and a block containing any versioned transaction will prompt an error.
