# JSON-RPC 方法

###  示例 RPC

{% tabs %}
{% tab title="Curl" %}

```
curl https://api.chainup.net/ethereum/mainnet/<YOUR_API_KEY> \
-X POST \
-H 'content-type: application/json' \
-H "CONSISTENT-HASH: true" \
--data '{"jsonrpc":"2.0","method":"net_peerCount","params":[],"id":1}' 
```

{% endtab %}

{% tab title="Javascript" %}

```
const axios = require('axios'); 
//npm install axios if you don have the module installed

let options = {
    url: "https://api.chainup.net/ethereum/mainnet/<YOUR_API_KEY>",
    method: "post",
    headers: {
        "content-type": "application/json",
        "CONSISTENT-HASH": "true"  // Add your custom header here
    },
    data: {"jsonrpc":"2.0","method":"net_peerCount","params":[],"id":1}
};

axios(options)
    .then(response => {
        console.log('Post successful: response:', response.data);
    })
    .catch(error => {
        console.error('An error has occurred:', error);
    });
```

{% endtab %}

{% tab title="Python" %}

```python
import requests
import json

headers = {
    "content-type": "application/json",
    "CONSISTENT-HASH": "true"  # Add your custom header here
}

payload = json.dumps({
    "id": 1,
    "jsonrpc": "2.0",
    "method": "net_peerCount",
    "params": []
})

url = "https://api.chainup.net/ethereum/mainnet/00164210c0334c76a235aca8b1dcf655"
r = requests.post(url=url, headers=headers, data=payload)

if r.status_code == 200:
    print("Post successful: response: ", r.content)
else:
    print("An error has occurred: ", r.status_code)

```
