| --------- | ------ | -------- | ------------------------------------ |
| address   | string | Yes      | Address in user-friendly base64 form |

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

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

#[tokio::main]

    let response = client
        .post("https://go.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
{
    "ok": true,
    "result": "0:ed16913070500471175e992b561d8de82d31fbf84910ced6eb5fc92e74485ef8a",
    "id": "getblock.io",
    "jsonrpc": "2.0"
}
```

{% endcode %}

## Response Parameters

| Field  | Type   | Description                                       |
| ------ | ------ | ------------------------------------------------- |
| result | string | Raw `workchain:hex` representation of the address |

## Use Cases

* Converting user input to the raw form expected by some low-level APIs
* Storage normalisation in databases (raw form is canonical)
* Workchain extraction from user-friendly addresses

## Error Handling

| Status Code | Error Message       | Cause                                       |
| ----------- | ------------------- | ------------------------------------------- |
| 403         | Forbidden           | Missing or invalid `<ACCESS-TOKEN>`         |
| 422         | Validation Error    | Request parameters are missing or malformed |
| 429         | Too Many Requests   | Rate limit exceeded for your plan           |
| 504         | Lite Server Timeout | Upstream TON liteserver timed out           |

## 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 %}
