# get\_block\_count - Monero

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

This method returns the number of blocks in the longest chain known to the node. It is the cheapest call for determining the current chain tip and is the standard way to poll for new blocks on Monero.

## Parameters

* None

## Request Example

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

```bash
curl --location --request POST 'https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc": "2.0",
    "method": "get_block_count",
    "params": {},
    "id": "getblock.io"
}'
```

{% endtab %}

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

```javascript
import axios from 'axios';

const data = JSON.stringify({
    "jsonrpc": "2.0",
    "method": "get_block_count",
    "params": {},
    "id": "getblock.io"
});

const config = {
    method: 'post',
    url: 'https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/',
    headers: {
        'Content-Type': 'application/json'
    },
    data: data
};

axios(config)
    .then(response => console.log(JSON.stringify(response.data, null, 2)))
    .catch(error => console.log(error));
```

{% endtab %}

{% tab title="Python (Requests)" %}

```python
import requests
import json

url = "https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/"

payload = json.dumps({
    "jsonrpc": "2.0",
    "method": "get_block_count",
    "params": {},
    "id": "getblock.io"
})

headers = {
    'Content-Type': 'application/json'
}

response = requests.post(url, headers=headers, data=payload)
print(response.text)
```

{% endtab %}

{% tab title="Rust (Reqwest)" %}

```rust
use reqwest::Client;
use serde_json::json;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new();

    let payload = json!({
        "jsonrpc": "2.0",
        "method": "get_block_count",
        "params": {},
        "id": "getblock.io"
});

    let response = client
        .post("https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/")
        .header("Content-Type", "application/json")
        .json(&payload)
        .send()
        .await?;

    let result: serde_json::Value = response.json().await?;
    println!("{:#?}", result);

    Ok(())
}
```

{% endtab %}
{% endtabs %}

## Response Example

{% code overflow="wrap" %}

```json
{
    "id": "getblock.io",
    "jsonrpc": "2.0",
    "result": {
        "count": 3194582,
        "status": "OK",
        "untrusted": false
    }
}
```

{% endcode %}

## Response Parameters

| Field            | Type         | Description                                                                            |
| ---------------- | ------------ | -------------------------------------------------------------------------------------- |
| result.count     | unsigned int | Number of blocks in the longest known chain                                            |
| result.status    | string       | General RPC error code; `OK` means success                                             |
| result.untrusted | boolean      | `true` if the response came from bootstrap mode (untrusted), `false` if served locally |

## Use Cases

* Polling for new blocks in indexers and explorers
* Determining the current chain tip before making other calls
* Health-checking the RPC endpoint
* Mining-pool block-height tracking

## Error Handling

| Status Code | Error Message     | Cause                                       |
| ----------- | ----------------- | ------------------------------------------- |
| 403         | Forbidden         | Missing or invalid `<ACCESS-TOKEN>`         |
| -32602      | Invalid params    | Request parameters are missing or malformed |
| 429         | Too Many Requests | Rate limit exceeded for your plan           |

## SDK Integration

{% tabs %}
{% tab title="monero-javascript" %}

```javascript
import monerojs from 'monero-javascript';

const daemon = await monerojs.connectToDaemonRpc('https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/');

// Most methods are exposed directly on the daemon client. For raw access:
const result = await daemon.getDaemonConnection().sendJsonRequest('get_block_count', {});
console.log(result);
```

{% endtab %}

{% tab title="monero-python" %}

```python
from monero.backends.jsonrpc import JSONRPCDaemon
from monero.daemon import Daemon

backend = JSONRPCDaemon(host='shared.eu-central-1.getblock.io', port=443, path='/<ACCESS-TOKEN>/', protocol='https')
daemon = Daemon(backend)

# For methods covered by the typed API, use the daemon attribute directly.
# For raw RPC access:
result = backend.raw_request('get_block_count', {})
print(result)
```
