The response follows the [standard format][], with a successful result containing the following fields:

Field	Type	Description
current_ledger_size	String (Integer)	Number of transactions provisionally included in the in-progress ledger.
current_queue_size	String (Integer)	Number of transactions currently queued for the next ledger.
drops	Object	Various information about the transaction cost (the Fee field of a transaction), in [drops of XRP][].
drops.base_fee	String (Integer)	The transaction cost required for a reference transaction to be included in a ledger under minimum load, represented in drops of XRP.
drops.median_fee	String (Integer)	An approximation of the median transaction cost among transactions included in the previous validated ledger, represented in drops of XRP.
drops.minimum_fee	String (Integer)	The minimum transaction cost for a reference transaction to be queued for a later ledger, represented in drops of XRP. If greater than base_fee, the transaction queue is full.
drops.open_ledger_fee	String (Integer)	The minimum transaction cost that a reference transaction must pay to be included in the current open ledger, represented in drops of XRP.
expected_ledger_size	String (Integer)	The approximate number of transactions expected to be included in the current ledger. This is based on the number of transactions in the previous ledger.
ledger_current_index	Number	The [Ledger Index][] of the current open ledger these stats describe. [New in: rippled 0.50.0][]
levels	Object	Various information about the transaction cost, in [fee levels][]. The ratio in fee levels applies to any transaction relative to the minimum cost of that particular transaction.
levels.median_level	String (Integer)	The median transaction cost among transactions in the previous validated ledger, represented in [fee levels][].
levels.minimum_level	String (Integer)	The minimum transaction cost required to be queued for a future ledger, represented in [fee levels][].
levels.open_ledger_level	String (Integer)	The minimum transaction cost required to be included in the current open ledger, represented in [fee levels][].
levels.reference_level	String (Integer)	The equivalent of the minimum transaction cost, represented in [fee levels][].
max_queue_size	String (Integer)	The maximum number of transactions that the transaction queue can currently hold.
