:::info[Info]
The [Rootstock RPC API Sandbox](https://rpc.rootstock.io/doc) is available on <Shield label="mainnet" title="testnet" tooltip="Available on Mainnet and Testnet" color="orange" />. To make live requests, you will need an API key. Follow the [Create an API Key guide](https://rpc.rootstock.io/doc/create-api-key) to create a free account and generate one.

## How to Use the RPC API Sandbox

<Steps>
  <Step title="Open the documentation">
    Navigate to [rpc.rootstock.io/doc](https://rpc.rootstock.io/doc). The **Get Started** page explains what the Rootstock RPC Service is and links to the Quick Start guides. The left sidebar is organized into three sections: **Introduction** (Get Started, the JSON-RPC Standard, and Quick Start Guides), **Sandbox** (instructions for running live requests), and **Methods**, a searchable list of every available JSON-RPC method.

    </div>
  </Step>

  <Step title="Get your API key and learn how the Sandbox works">
    Click **Instructions** under **Sandbox** to see how live requests work: every method page includes a Sandbox that sends real requests to the Rootstock RPC Service using your API key and displays the response.

    Don't have an API key yet? Go to the **Create an API Key** guide under **Quick Start Guides** to sign up on the [Rootstock RPC dashboard](https://rpc.rootstock.io/) and generate one. Paste this key directly into the method page in the next step.

    </div>
  </Step>

  <Step title="Select a method, set your key and network, and run it">
    Browse the method list in the left sidebar or use **Search methods** to find one. Each method page shows:

    - A description of what it returns, its required **Path parameters** (your `apiKey`), and any method **Parameters**.
    - **Tips** and **Notes** with practical guidance. For example, `eth_blockNumber` returns the block number in hexadecimal, so use `parseInt(result, 16)` to convert it to decimal.
    - An **Example request** panel on the right with a ready-to-copy cURL (or other language) snippet pre-filled with your endpoint.

    Click the endpoint URL to switch between **Rootstock Mainnet** and **Rootstock Testnet**, paste your API key in the `apiKey` field, and fill in any required parameters. Click **Run** to send a live request and see the JSON response in the **Response** panel below.
