  async function testConnection() {
    try {
      const score = await client.getScore('alice.zks');

    } catch (error) {
      console.error('SDK error:', error);
    }
  }
  ```

  ```python Python theme={null}
  from zkscore import ZKScoreClient

  client = ZKScoreClient(api_key='your_api_key')

  async def test_connection():
      try:
