# net\_listening - Ethereum

This method returns whether the node is actively listening for network connections from peers. On managed RPC endpoints the response is virtually always `true` — the field's diagnostic value is highest on self-hosted nodes where isolation from the P2P network indicates a configuration or connectivity issue.

## Parameters

This method takes no parameters.

## Request

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

{% endcode %}

{% tab title="Axios" %}
{% code title="example.js" %}

```javascript
const axios = require('axios');

const response = await axios.post('https://go.getblock.io/<ACCESS-TOKEN>/', {
    jsonrpc: '2.0',
    method: 'net_listening',
    params: [],
    id: 'getblock.io'
}, {
    headers: { 'Content-Type': 'application/json' }
});

console.log(response.data.result);
```

```rust
use reqwest::Client;
use serde_json::{json, Value};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new();
    
    let response = client
        .post("https://go.getblock.io/<ACCESS-TOKEN>/")
        .header("Content-Type", "application/json")
        .json(&json!({
            "jsonrpc": "2.0",
            "method": "net_listening",
            "params": [],
            "id": "getblock.io"
        }))
        .send()
        .await?
        .json::<Value>()
        .await?;
    
    println!("Result: {}", response["result"]);
    Ok(())
}
```

{% endcode %}
{% endtab %}
{% endtabs %}

## Response

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

## Response Parameters

| Parameter | Type    | Description                                                                                       |
| --------- | ------- | ------------------------------------------------------------------------------------------------- |
| `jsonrpc` | string  | JSON-RPC protocol version ("2.0")                                                                 |
| `id`      | string  | Request identifier matching the request                                                           |
| `result`  | boolean | `true` if the node is listening for peers, `false` if the P2P listener is disabled or unreachable |

## Use Cases

* **Node Health Probes**: Basic reachability check as part of an endpoint availability monitor
* **Self-Hosted Node Diagnostics**: Detect P2P isolation on a self-run node (managed endpoints won't return `false` in normal operation)
* **Load Balancer Health Checks**: Simple boolean liveness probe for infrastructure-level health checks

## Error Handling

| Error Code | Message        | Description                                        |
| ---------- | -------------- | -------------------------------------------------- |
| -32603     | Internal error | Node's P2P listener status could not be determined |

## Web3 Integration

{% tabs %}
{% tab title="Ethers.js" %}
{% code title="ethers-example.js" %}

```javascript
import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider('https://go.getblock.io/<ACCESS-TOKEN>/');

const isListening = await provider.send('net_listening', []);
console.log('Listening for peers:', isListening);
```

{% endcode %}
{% endtab %}

{% tab title="Viem" %}
{% code title="viem-example.js" %}

```javascript
import { createPublicClient, http } from 'viem';
import { mainnet } from 'viem/chains';

const client = createPublicClient({
    chain: mainnet,
    transport: http('https://go.getblock.io/<ACCESS-TOKEN>/'),
});

const isListening = await client.request({ method: 'net_listening' });
console.log('Listening for peers:', isListening);
```

{% endcode %}
{% endtab %}
{% endtabs %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.getblock.io/api-reference/ethereum-eth/net_listening-ethereum.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
