eth_gasPrice - ARC

Example code for the eth_gasPrice JSON-RPC method. Complete guide on how to use eth_gasPrice JSON-RPC in GetBlock Web3 documentation.

This method returns the node's current suggested gas price, denominated in USDC base units (not wei). Multiply by gasUsed to get the total USDC cost of a transaction. Arc's dollar-denominated fees make cost forecasting predictable in ways that volatile gas-token chains cannot match.

Parameters

None

Request Example

curl --location --request POST 'https://go.getblock.io/<ACCESS-TOKEN>/' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc": "2.0",
    "method": "eth_gasPrice",
    "params": [],
    "id": "getblock.io"
}'

import requests
import json

url = "https://go.getblock.io/<ACCESS-TOKEN>/"

payload = json.dumps({
    "jsonrpc": "2.0",
    "method": "eth_gasPrice",
    "params": [],
    "id": "getblock.io"
})

headers = {
    'Content-Type': 'application/json'
}

response = requests.post(url, headers=headers, data=payload)
print(response.text)

use reqwest::Client;
use serde_json::json;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    const client = Client::new();

    let payload = json!({
        "jsonrpc": "2.0",
        "method": "eth_gasPrice",
        "params": [],
        "id": "getblock.io"
    });

    let response = client
        .post("https://go.getblock.io/<ACCESS-TOKEN>/")
        .header("Content-Type", "application/json")
        .json(&payload)
        .send()
        .await?;

    let result: serde_json::Value = response.json().await?;
    println!("{:#?}", result);

    Ok(())
}

Response Example

{
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "result": "0x3b9aca00"
}

Response Parameters

Field

Type

Description

result

string

Current suggested gas price in USDC base units (hex). To convert to USDC, divide by 10⁶

Use Cases

Setting gasPrice on legacy transactions
Fallback for clients that don't support EIP-1559
Forecasting USDC payment costs before broadcast
Merchant invoicing systems that need predictable fee budgets
