# Plugins HTTP API

The `/plugin` endpoints are used to query for and interact with
dynamic plugins. Currently only Container Storage Interface (CSI)
plugins are dynamic.

## List Plugins

This endpoint lists all dynamic plugins.

| Method | Path          | Produces           |
| ------ | ------------- | ------------------ |
| `GET`  | `/v1/plugins` | `application/json` |

The table below shows this endpoint's support for
[blocking queries](/api-docs#blocking-queries) and
[required ACLs](/api-docs#acls).

| Blocking Queries | ACL Required                |
| ---------------- | --------------------------- |
| `YES`            | `namespace:csi-list-plugin` |

### Parameters

- `type` `(string: "")`- Specifies the type of plugin to
  query. Currently only supports `csi`. This is specified as a query
  string parameter. Returns an empty list if omitted.

### Sample Request

```shell-session
$ curl \
    https://localhost:4646/v1/plugins?type=csi
```

### Sample Response

```json
[
  {
    "ID": "example",
    "Provider": "aws.ebs",
    "ControllerRequired": true,
    "ControllersHealthy": 2,
    "ControllersExpected": 3,
