# rungetmethod - TON

Example code for the rungetmethod JSON-RPC method. Сomplete guide on how to use rungetmethod JSON-RPC in GetBlock.io Web3 documentation.

This method invokes a read-only get-method on a TON smart contract and returns the TVM stack result. Get-methods do not change contract state and incur no fees — they are the standard way to query contract-defined data such as Jetton wallet balances or NFT metadata.

## Parameters

| Parameter | Type              | Required | Description                                                   |
| --------- | ----------------- | -------- | ------------------------------------------------------------- |
| address   | string            | Yes      | Address of the smart contract                                 |
| method    | string or integer | Yes      | Method name (e.g. `get_wallet_data`) or its numeric method-id |
| stack     | array             | Yes      | Input arguments as TVM stack entries, e.g. `[["num", "42"]]`  |

## SDK Integration

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

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

const client = new TonClient({
    endpoint: 'https://shared.eu-central-1.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.
```
