# Check Team Ownership

> Whether the authenticated caller is the team owner.

Returns `{ is_owner: true }` when the caller holds the `owner` role on the active team. Several billing actions (subscribing, cancelling, buying top-ups) are owner-only — clients use this to decide whether to show or disable those controls.

## Response

```json 200 theme={null}
{
  "is_owner": true
}
```

### Fields

<ResponseField name="is_owner" type="boolean">
  `true` when the caller's `team_members.role` is `owner` on the
  currently selected team, `false` otherwise.
</ResponseField>

## Example

```bash cURL theme={null}
curl https://api.supapost.so/billing/is-owner \
  -H "Authorization: Bearer YOUR_API_KEY"
```
