const { Web3 } = require("web3");
const NODE_URL = "CHAINSTACK_NODE_URL";
const web3 = new Web3(NODE_URL);

async function getGasPrice() {
    const baseFee = await web3.eth.getGasPrice();
    const feeInGwei = web3.utils.fromWei(baseFee, "gwei")
    console.log(`The base gas fee is: ${baseFee} Wei`);
    console.log(`The base gas fee is: ${feeInGwei} Gwei`);
  }

const ethers = require('ethers');
const NODE_URL = "CHAINSTACK_NODE_URL";
const provider = new ethers.JsonRpcProvider(node_url);

async function getGasPrice() {
  const baseFee = await provider.send("eth_gasPrice");
  console.log(`The base gas fee is: ${baseFee} Wei`);
}

getGasPrice()

from web3 import Web3  
node_url = "CHAINSTACK_NODE_URL"

web3 = Web3(Web3.HTTPProvider(node_url)) 
print(web3.eth.gas_price)  

Use case

You can use eth_gasPrice to calculate the total gas value to send with a transaction based on the base and priority fee system. Ethereum's London hard fork implemented This concept with EIP-1559.

EIP-1559 aimed to solve the problem of network congestion by implementing a dynamic fee market mechanism, which adjusts the fee required to process a transaction based on network demand. With the current system, the total gas price comprises a base fee determined by the network's load and a priority fee added by the user.

Note

The eth_gasPrice method returns the base fee.
