{% code lineNumbers="true" %}

```bash
curl -X GET "https://wdk-api.tether.io/api/v1/ethereum/usdt/0xdac17f958d2ee523a2206206994597c13d831ec7/token-balances" \
     -H "x-api-key: your-api-key-here"
```

{% endcode %}
{% endtab %}

{% tab title="JavaScript" %}
{% code lineNumbers="true" %}

```javascript
const axios = require('axios');

async function getTokenBalance(blockchain, token, address) {
  const response = await axios.get(
    `https://wdk-api.tether.io/api/v1/${blockchain}/${token}/${address}/token-balances`,
    {
      headers: {
        'x-api-key': 'your-api-key-here'
      }
    }
  );
  
  return response.data.tokenBalance;
}

const balance = await getTokenBalance('ethereum', 'usdt', '0xdac17f958d2ee523a2206206994597c13d831ec7');
console.log(`Balance: ${balance.amount} ${balance.token.toUpperCase()}`);
```

{% endcode %}
{% endtab %}
