## Examples for Console REST API Requests

#### cURL

Most \*nix-based systems come with cURL pre-installed. cURL is a command-line tool and library for transferring data with URLs. To check if cURL is installed, run the following command:

```json
curl -h
```

Example of requesting the latest block number using the GetBlock API and cURL:

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

#### Python

To run Python examples, ensure Python is installed along with the requests package. You can install the package using the following command:

```json
python -m pip install requests
```

Example:

```python
import requests
url = "https://go.getblock.io/<ACCESS-TOKEN>/"
headers = { "Content-Type": "application/json" }
payload = { "jsonrpc": "2.0", "method": "eth_blockNumber", "params": [], "id": "getblock.io" }
response = requests.post(url, headers=headers, json=payload)
print(response.json())
```

#### JavaScript

For JavaScript examples, you'll need Node.js version 18 or later. Follow the official documentation to install the latest stable version globally. Verify your installation by running:

```
node -v
```

#### Ruby
