# Namespaces API **(FREE)**

Usernames and group names fall under a special category called
[namespaces](../user/namespace/index.md).

For users and groups supported API calls see the [users](users.md) and
[groups](groups.md) documentation respectively.

[Pagination](index.md#pagination) is used.

## List namespaces

Get a list of the namespaces of the authenticated user. If the user is an
administrator, a list of all namespaces in the GitLab instance is shown.

```plaintext
GET /namespaces
GET /namespaces?search=foobar
GET /namespaces?owned_only=true
```

| Attribute    | Type    | Required | Description |
| ------------ | ------- | -------- | ----------- |
| `search`     | string  | no       | Returns a list of namespaces the user is authorized to view based on the search criteria |
| `owned_only` | boolean | no       | In GitLab 14.2 and later, returns a list of owned namespaces only |

Example request:

```shell
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/namespaces"
```

Example response:

```json
[
  {
    "id": 1,
    "name": "user1",
    "path": "user1",
    "kind": "user",
    "full_path": "user1",
    "parent_id": null,
    "avatar_url": "https://secure.gravatar.com/avatar/e64c7d89f26bd1972efa854d13d7dd61?s=80&d=identicon",
    "web_url": "https://gitlab.example.com/user1",
    "billable_members_count": 1,
    "plan": "default",
    "trial_ends_on": null,
    "trial": false
  },
  {
    "id": 2,
    "name": "group1",
    "path": "group1",
    "kind": "group",
    "full_path": "group1",
    "parent_id": null,
    "avatar_url": null,
    "web_url": "https://gitlab.example.com/groups/group1",
    "members_count_with_descendants": 2,
    "billable_members_count": 2,
    "plan": "default",
    "trial_ends_on": null,
    "trial": false
  },
  {
    "id": 3,
    "name": "bar",
    "path": "bar",
    "kind": "group",
    "full_path": "foo/bar",
    "parent_id": 9,
    "avatar_url": null,
    "web_url": "https://gitlab.example.com/groups/foo/bar",
    "members_count_with_descendants": 5,
    "billable_members_count": 5,
    "plan": "default",
    "trial_ends_on": null,
    "trial": false
  }
]
```

Owners also see the `plan` property associated with a namespace:

```json
[
  {
    "id": 1,
    "name": "user1",
    "plan": "silver",
    ...
  }
]
```

Users on GitLab.com also see `max_seats_used` and `seats_in_use` parameters.
`max_seats_used` is the highest number of users the group had. `seats_in_use` is
the number of license seats currently being used. Both values are updated
once a day.

`max_seats_used` and `seats_in_use` are non-zero only for namespaces on paid plans.

```json
[
  {
    "id": 1,
    "name": "user1",
    "billable_members_count": 2,
    "max_seats_used": 3,
    "seats_in_use": 2,
    ...
  }
]
```

NOTE:
Only group owners are presented with `members_count_with_descendants` and `plan`.
