# GET /v1/xrpl/fee

Current XRPL fee tiers in drops with a congestion score.

## Purpose

Returns economy, standard and priority fees in drops plus a 0-100 congestion score and band (`low`, `medium`, `high`) computed from queue fill, open-ledger fee pressure and load factor.

## When to use

Before submitting a transaction, to choose a `Fee` and to decide whether the network is congested.

## When not to use

Not a price feed and not a historical series; it describes the latest validated ledger only.

## Parameters

This endpoint takes no parameters.
