Name	MetricID	Unit	Interval
Block Maximum Fees	block_fee_max	Native Currency	1 block

Methodology

The most recently-mined block is evaluated and the maximum of fees in that block is computed.

Available Assets

Bitcoin (BTC), Ethereum (ETH)*

* Historical data covering the pre-merge timeframe only (up to 9/15/2022). With the merge ETH switched from Proof of Work and miners to Proof of Stake and validators meaning the miner fees per block are non-existent post the merge date for Ethereum.

API Endpoints

metrics can be accessed using these endpoints:

• timeseries/asset-metrics

and by passing in the metric ID's block_fee* in the metrics parameter.

Asset metrics

Returns requested metrics for specified assets. Results for block by block metrics (1b frequency) are ordered by tuple (asset, height, block_hash), all other metrics are ordered by tuple (asset, time). You can change the sorting using sort query parameter. Supported output formats are json (default) and csv, use format query parameter to override it. To fetch the next page of results use next_page_url JSON response field or x-next-page-url CSV HTTP header if present. If multiple metrics are requested in the same time the strict policy for partially available metrics among requested ones is applied:

GEThttps://api.coinmetrics.io/v4/timeseries/asset-metrics
