# eth\_gasPrice - Scroll

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 current legacy gas price in wei, as a hex-encoded integer. On GIWA Sepolia it reflects the L2 execution gas price and is used for legacy (non-EIP-1559) transactions.

## Parameters

{% hint style="info" %}
This method does not require any parameters. Send the request with an empty `params` array.
{% endhint %}

## Response

```json
{
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "result": "0xf4240"
}
```

## Response Parameters

| Parameter | Type   | Description                             |
| --------- | ------ | --------------------------------------- |
| jsonrpc   | string | JSON-RPC protocol version ("2.0")       |
| id        | string | Request identifier matching the request |
| result    | string | Hex-encoded gas price in wei            |

## Use Cases

* **Legacy Pricing**: Set gasPrice on type-0 transactions for tooling that predates EIP-1559
* **Fee Estimates**: Show an approximate execution fee before a user signs
* **Cost Monitoring**: Track L2 execution gas price over time
* **Batch Planning**: Decide when execution costs are low enough to submit queued work

## Error Handling

| Error Code | Message          | Description                                    |
| ---------- | ---------------- | ---------------------------------------------- |
| -32603     | Internal error   | The node failed to compute the gas price       |
| -32601     | Method not found | The eth module is disabled on the client build |
