I would like to get the historical Gas (Gwei) price in hourly or minutely with safelow, Standard, fast and fastest. I am aware of the etherscan.io which gives avg gas price for a day and also ethstation which gives realtime data. I am able to get the real-time from https://www.etherchain.org/tools/gasPriceOracle. Is there a way where i can get historical prices?

You can follow this website they have provided their API as well click here

and you can get a lot of other detailed information as well


You can get the historical data from the Chainlink Price feeds fast gas proxy contract if you wanted to pull from an on-chain record.

You can see the history right in the contract

/** This example code is designed to quickly deploy an example contract using Remix.

pragma solidity ^0.6.7;

import "https://github.com/smartcontractkit/chainlink/blob/master/evm-contracts/src/v0.6/interfaces/AggregatorV3Interface.sol";

contract HistoricalPriceConsumerV3 {

    AggregatorV3Interface internal priceFeed;
     * Network: Mainnet
     * Aggregator: Fast Gas / Gwei Price
     * Address: 0x169E633A2D1E6c10dD91238Ba11c4A708dfEF37C
    constructor() public {
        priceFeed = AggregatorV3Interface(0x169E633A2D1E6c10dD91238Ba11c4A708dfEF37C);

     * Returns historical price for a round id.
     * roundId is NOT incremental. Not all roundIds are valid.
     * You must know a valid roundId before consuming historical data.
     *    InValid:      18446744073709562300
     *    Valid:        18446744073709562301
     * @dev A timestamp with zero value means the round is not complete and should not be used.
    function getHistoricalPrice(uint80 roundId) public view returns (int256) {
            uint80 id, 
            int price,
            uint startedAt,
            uint timeStamp,
            uint80 answeredInRound
        ) = priceFeed.getRoundData(roundId);
        require(timeStamp > 0, "Round not complete");
        return price;

Since all the truly full length historic sources are paid in some-way, you should be able to materialize a view in bigquery using the public crypto datasets that is SQL accessible if that works for you.

Here's what I'm using:

DATE(block_timestamp) as block_date,
Format("%.*f",3,(AVG(gas_price)/1000000000)) as avg_gas_price 
FROM `bigquery-public-data.crypto_ethereum.transactions` 
-- WHERE DATE(block_timestamp) > "2022-02-20"
group by 1
order by 1 desc

That's daily level granularity but you can break out the block_timestamp by minute or hour if you need it.

If you can provide an algorithm for calculating safelow, standard, fast, and fastest I will build that in as well and update this answer.

Edit: more information on the crypto_ethereum.transaction data "source" enter image description here


I've been able to hone in on some estimates for different transaction types that can be used to calculate the costs for those transactions historically.

It goes something like this:

standard_trans_eth = 21000 * avg_gas_price / 1e9
erc20_trans_eth = 65000 * avg_gas_price / 1e9
stablecoin_swap_eth = 100000 * avg_gas_price / 1e9
token_swap_eth = 200000 * avg_gas_price / 1e9
pool_deposit_eth = 300000 * avg_gas_price / 1e9
nft_mint_721_eth = 350000 * avg_gas_price / 1e9
nft_mint_1155_eth = 150000 * avg_gas_price / 1e9 
ico_contract_eth = 1000000 * avg_gas_price / 1e9

If you want the resulting price in usd, just multiply that _eth column by the historic price of eth at the time.

Example: Jan 21, 2022 when avg gas price was 185.589 & ETH opened ~3000 USD, closed ~2500 USD.

standard_trans_eth = 21000 gas limit * 186 gwei / 1e9 * $2750 usd = $10.75

Going to be working on a complete visualization / dataset of this in bigquery but this is how I'm working it so far.


Highly recommend using the "Estimated Cost of Transactions" table for representative gas limits from: https://etherchain.org/tools/gasnow


The closest you can get is using this graph of historical gas prices.

Unless somebody has been storing the data you are asking for in a database, you will not be able to retrieve it. You can, however, run the same algorithm that ethgasstation.info uses on the graph above and interpolate the data, if desired.
