## Block Maximum Feerate <a href="#block_feerate_max" id="block_feerate_max"></a>

**Definition**

A block's maximum transaction feerate. For Bitcoin this is measured in sats/vbyte. For Ethereum this measures the gas price in Gwei

**Dictionary**

<table data-header-hidden><thead><tr><th width="180"></th><th width="210"></th><th width="107"></th><th></th></tr></thead><tbody><tr><td>Name</td><td>MetricID</td><td>Unit</td><td>Interval</td></tr><tr><td>Block Maximum Feerate</td><td>block_feerate_max</td><td>Native feerate</td><td>1 block</td></tr></tbody></table>

**Methodology**

The most recent block is evaluated and the maximum feerate in that block is computed.

**Available Assets**

Bitcoin (BTC), Ethereum (ETH)

## API Endpoints

Transaction Feerate metrics can be accessed using these endpoints:

* `timeseries/asset-metrics`

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