## SDK Integration

{% 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://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/ext/bc/X', {
    jsonrpc: '2.0',

    params: {"assetID": "FvwEAhmxKfeiG8SnEvq42hc6whRyY3EFYAvebMqDNDGCgxN5Z"}
}});
console.log(response.data);
```

{% endtab %}
