Syntax

public static class NetworkFeesExtensions

Methods

GetLatestNetworkFeesAsync(MirrorRestClient)

Retrieves the current network fee schedule via /api/v1/network/fees (no timestamp filter). The mirror node returns the most recent snapshot it has ingested.

Declaration

public static Task<NetworkFeesData?> GetLatestNetworkFeesAsync(this MirrorRestClient client)

Parameters

Type	Name	Description
MirrorRestClient	client	Mirror Rest Client to use for the request.

Returns

Type	Description
Task<NetworkFeesData>	The current Network fee data or null if not found.

GetNetworkFeesAsync(MirrorRestClient, ConsensusTimeStamp)

Retrieves the network fee schedule active at (or before) the given consensus timestamp via /api/v1/network/fees?timestamp=lte:{consensus}. Useful for reconstructing historical fee conditions for a specific transaction.

Declaration

public static Task<NetworkFeesData?> GetNetworkFeesAsync(this MirrorRestClient client, ConsensusTimeStamp consensus)

Parameters

Type	Name	Description
MirrorRestClient	client	Mirror Rest Client to use for the request.
ConsensusTimeStamp	consensus	Timestamp to retrieve the network fee schedule at or before.

Returns

Type	Description
Task<NetworkFeesData>	The fee schedule in effect at the requested timestamp, or null if the mirror node has no snapshot from that era.

Remarks

For the current fee schedule, call GetLatestNetworkFeesAsync(MirrorRestClient) instead — it skips the timestamp filter and lets the server return the most recent snapshot.
