# Handle SDK errors

> Catch transport, API, and validation failures from the Python SDK.

All SDK exceptions inherit from `ValkyrieSDKError`:

```python theme={null}
from valkyrie.sdk import ValkyrieAPIError, ValkyrieSDKError

try:
    run = await client.runs.fetch(run_id)
except ValkyrieAPIError as exc:
    print(exc.status_code, exc.detail)
except ValkyrieSDKError as exc:
    print(exc)
```

Catch `ValkyrieAPIError` when the tracker returned an HTTP error and you need its status or detail. Catch `ValkyrieSDKError` for a common boundary around all SDK failures. The [errors reference](/reference/sdk/errors) lists every exception and its parent.
