## Error Handling

<CodeGroup>
  ```python Python theme={"dark"}
  from terminaluse import TerminalUse, UnprocessableEntityError

  client = TerminalUse()

  try:
      agent = client.agents.retrieve("id")
  except UnprocessableEntityError as e:
      print(f"Validation error: {e}")
  except Exception as e:
      print(f"Error: {e}")
  ```

  ```typescript TypeScript theme={"dark"}
  import { TerminalUseClient, TerminalUseError } from '@terminaluse/sdk';

  const client = new TerminalUseClient({
    environment: process.env.TERMINALUSE_BASE_URL ?? 'https://api.terminaluse.com',
    bearerAuth: { token: process.env.TERMINALUSE_API_KEY! },
  });

  try {
    const agent = await client.agents.retrieve({ agent_id: 'id' });
  } catch (e) {
    if (e instanceof TerminalUseError) {
      console.log(`Error ${e.statusCode}: ${e.message}`);
    }
  }
  ```
</CodeGroup>

## Retries

The SDK automatically retries on 408, 429, and 5xx errors (default: 2 retries).

```python theme={"dark"}
client = TerminalUse(max_retries=5)  # or 0 to disable
```

```typescript theme={"dark"}
const client = new TerminalUseClient({
  environment: process.env.TERMINALUSE_BASE_URL ?? 'https://api.terminaluse.com',
  bearerAuth: { token: process.env.TERMINALUSE_API_KEY! },
  maxRetries: 5,
});
```
