### Fetching Feature Toggles

`GET: http://unleash.host.com/api/admin/features`

This endpoint is the one all admin ui should use to fetch all available feature toggles from the _unleash-server_. The response returns all active feature toggles and their current strategy configuration. A feature toggle will have _at least_ one configured strategy. A strategy will have a `name` and `parameters` map.

**Example response:**

```json
{

  "features": [
    {
      "name": "Feature.A",

      "enabled": false,
      "stale": false,
