# net\_info - Cosmos

Example code for the net\_info JSON-RPC method. Complete guide on how to use net\_info JSON-RPC in GetBlock Web3 documentation.

Returns information about the node's network — number of peers, listening status, and per-peer connection details.

## Parameters

* None

## Request Example

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

```bash
# JSON-RPC over HTTP POST (canonical)
curl --location --request POST 'https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc": "2.0",
    "method": "net_info",
    "params": [],
    "id": "getblock.io"
}'

# URI over HTTP GET (alternate, for simple methods)
curl --location --request GET 'https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/net_info'
```

{% endtab %}

{% tab title="JavaScript (Axios)" %}

```javascript

    "method": "net_info",
    "params": [],
    "id": "getblock.io"
});

const config = {
    method: 'post',
    url: 'https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/',
    headers: {

## SDK Integration

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

```javascript
import { Tendermint37Client, HttpClient } from '@cosmjs/tendermint-rpc';

const httpClient = new HttpClient('https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/');
const client = await Tendermint37Client.create(httpClient);

// CosmJS exposes typed methods on the client (e.g. client.status(), client.block()).
// For raw access to any RPC method:
const result = await httpClient.execute({"jsonrpc": "2.0", "id": "getblock.io", "method": "net_info", "params": []});
console.log(result);
```

{% endtab %}

{% tab title="cosmpy / requests" %}

```python
# cosmpy wraps Cosmos REST / gRPC. For raw CometBFT RPC access, use requests.
import requests

response = requests.post('https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/', json={
    'jsonrpc': '2.0',
    'id': 'getblock.io',
    'method': 'net_info',
    'params': []
}})
