Parameters

blockCount

string/integer

REQUIRED

The number of blocks in the requested range. Between 1 and 1024 blocks can be requested in a single query. It will return less than the requested range if not all blocks are available

newestBlock

string

REQUIRED

The highest number block of the requested range in hexadecimal format or tags. The supported tag values include earliest for the earliest/genesis block, latest for the latest mined block, pending for the pending state/transactions, safe for the most recent secure block, and finalized for the most recent secure block accepted by more than 2/3 of validators

rewardPercentiles

array

REQUIRED

A list of percentile values with a monotonic increase in value. The transactions will be ranked by effective tip per gas for each block in the requested range, and the corresponding effective tip for the percentile will be calculated while taking gas consumption into consideration

Returns

oldestBlock

string

The lowest number block of the returned range encoded in hexadecimal format

baseFeePerGas

array

An array of block base fees per gas. This includes the next block after the newest of the returned range, because this value can be derived from the newest block. Zeroes are returned for pre-EIP-1559 blocks

gasUsedRatio

array

An array of block gas used ratios. These are calculated as the ratio of gasUsed and gasLimit

reward

array

(Optional) An array of effective priority fees per gas data points from a single block. All zeroes are returned if the block is empty

baseFeePerBlobGas

array

The base fee per unit of blob gas (in hexadecimal) for a set of blocks

blobGasUsedRatio

array

The ratio of blob gas used to the blob gas limit
