POSTeth_feeHistory

injective Mainnethttps://evm-injective-mainnet.nodit.io/

Returns gas fee history for the requested block range. Use this to set appropriate values for maxFeePerGas and maxPriorityFeePerGas when creating transactions.

Request Body

methodstringrequired
paramsoneOf[]required

Pass the following parameters as an array with the appropriate types.

  1. block count: Number of blocks to query (1-1024). Fewer blocks may be returned if not all are available.
  2. newest block: The reference block for the query. Block number as hex string or "latest".
  3. reward percentiles: Integer array for sampling priority fee percentiles. Percentiles are weighted by gas used per block. Values 0-100 in ascending order.
params[0]integer

The number of blocks to query. Enter an integer from 1 to 1024. Fewer blocks than requested may be returned if not all blocks are available.

params[1]string

Use one of block number or block tag to specify a block.

  • Block number: hex string (ex. "0x1")
  • Block tag: enum string (ex. "latest", "earliest", "pending")
    • earliest: The oldest available block on the chain.
    • finalized: A recently finalized block that can no longer be changed. Primarily used in proof-of-stake (PoS) blockchains.
    • safe: A recent block considered safe by the network (immune to reorgs).
    • latest: The most recent block on the chain (may be subject to reorgs).
    • pending: The next block to be mined, including pending transactions in the mempool.
params[2]integer[]

An array of percentile values used to sample priority fees. Percentiles are weighted by the gas used in each block. Enter integers from 0 to 100 in ascending order.

Responses
oldestBlockstring

Oldest block number in the returned range (hex)

rewardstring[][]

Array of priority fees at requested percentiles for each block (in wei, hex)

baseFeePerGasstring[]

Array of base fees per gas for each block (in wei, hex). Last element is the next block's expected value.

gasUsedRationumber[]

Array of gas utilization ratios per block (0 to 1)
