## SDK Integration

{% tabs %}
{% tab title="AvalancheJS / Axios" %}

```javascript
// AvalancheJS provides typed clients for P-Chain and X-Chain.
// X-Chain operations are exposed through `avm` in AvalancheJS.
// For raw JSON-RPC access, use a generic HTTP client as in the Request Example.
import axios from 'axios';

const response = await axios.post('https://go.getblock.io/<ACCESS-TOKEN>/ext/bc/X', {
    jsonrpc: '2.0',
    id: 'getblock.io',
    method: 'avm.getTx',
    params: {
        txID: "2kxwWpHvZPhMsJcSTmM7a3Da7sExB8pPyF7t4cr2NSwnYqNHni",
        encoding: "json"
    }
});
console.log(response.data);
```

{% endtab %}

{% tab title="Python" %}

```python
# AvalancheJS is JavaScript-only. For Python, use a generic JSON-RPC client.
import requests
import json

url = 'https://go.getblock.io/<ACCESS-TOKEN>/ext/bc/X'
payload = {
    'jsonrpc': '2.0',
    'id': 'getblock.io',
