# getaddressinformation - TON

This method returns basic information about a TON address, including its balance in nanotons, account state, contract code, contract data, and the identifier of the last transaction. It is the most commonly used method for reading account state on TON.

## Parameters

| Parameter | Type    | Required | Description                                                                                           |
| --------- | ------- | -------- | ----------------------------------------------------------------------------------------------------- |
| address   | string  | Yes      | Identifier of the target TON account in any form (user-friendly `EQ…` / `UQ…` or raw `workchain:hex`) |
| seqno     | integer | No       | Masterchain seqno at which to read state. Defaults to the latest block                                |

## SDK Integration

{% tabs %}
{% tab title="@ton/ton (JavaScript)" %}

```javascript
import { TonClient } from '@ton/ton';

const client = new TonClient({
    endpoint: 'https://go.getblock.io/<ACCESS-TOKEN>/'
});

// The @ton/ton client wraps the same JSON-RPC methods.
// For low-level access, use client.callGetMethod or client.provider.
```

{% endtab %}

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

```python
from pytoniq import LiteClient
# For HTTP API access, use ton-http-client or call the JSON-RPC
# endpoint directly with requests as shown in the Request Example.
```

{% endtab %}
{% endtabs %}
