Bug in ApiObject __repr__: KeyError: <class 'type'>

```
/api_object.py", line 41, in __repr__
KeyError: <class 'type'>
```

The code:
```

    def __repr__(self):
        return f'<API:{self._data[type]}:{self._data[id]}>'
```

It seems like the fields `type` and `id` were supposed to be quoted?
