# View a Version

You can retrieve information about a Roboflow version using the Python SDK, REST API, and CLI.

### Version ID

Each version generated in Roboflow has a sequential, numerical ID associated with it. You can see that through the app on your versions page or by listing your project versions in the API.

{% tabs %}
{% tab title="Python" %}
To retrieve information about a project, use this command:

```python
import roboflow

rf = roboflow.Roboflow(api_key=YOUR_API_KEY_HERE)

# get a project
project = rf.workspace().project("PROJECT_ID")

model = project.version("1").model
```

The `model` variable contains the following JSON values:

```json
{
  "id": "mug-detector-eocwp/12",
  "name": "Mug Detector",
  "version": "12",
  "classes": null,
  "overlap": 30,
  "confidence": 40,
  "stroke": 1,
  "labels": false,
  "format": "json",
  "base_url": "https://detect.roboflow.com/"
}
```

{% endtab %}

{% tab title="REST API" %}
If you already know which project and version you want to retrieve information about, you can use the `/:workspace/:project/:version` endpoint. It returns similar information as the project endpoint but does not enumerate all of the project's other versions.

To retrieve information about a project, make a GET request to the following endpoint:

```url
https://api.roboflow.com/roboflow/chess-sample-4ckfl/1?api_key=$ROBOFLOW_API_KEY
```

This endpoint returns the following response:

To retrieve information about a project using the CLI, you can use the following command:

```
roboflow project get <project-id>
```

For more details regarding this CLI command, please refer to the [`roboflow project get`](https://github.com/roboflow/roboflow-python/blob/main/CLI-COMMANDS.md#example-get-workspace-details) section of the CLI docs.

### Keypoint Detection Skeletons

Keypoint Detection project versions will contain a `skeletons` field which contains your version skeletons for each class. For example, a project with a class `person` might have the following skeleton:

```json
{
...
"skeletons": {
    "person": {
        "vertices": [
            {
                "color": "#FF8000",
                "id": 0,
                "name": "nose",
                "x": 0.4546,
                "y": 0.18859999999999996
            },
            {
                "color": "#FF00FF",
                "id": 1,
                "name": "left_eye"
                "x": 0.478,
                "y": 0.1606
            },
            ...
        ],
        "edges": [
            {
                "color": "#00FFCE",
                "from": 13,
                "to": 15
            },
            ...
        ],
        "symmetries": [
            {
                "direction": "horizontal",
                "points": [1, 2]
            },
            ...
        ]
    }
}
```

Note, vertices should be accessed by index with inference predictions `class_id`. Then, vertex `id` can be used to reference edge (from/to) and symmetries (points).
