Mempool Average Relative Fee

GET https://api.glassnode.com/v1/metrics/mempool/fees_average_relative

The mean relative fee of transactions waiting in the mempool. The relative fee is calculated as the total transaction fees divided by the transacion size (in vByte). High relative fees give an indication of transaction urgency as miners do not consider total transaction fee but fee per size, as the total fee they can collect is limited by the block space.
