# List External Keys

`$client->organization->externalKeys->list(?int limit, ?string page): PageCursor<ExternalKey>`

**GET** `/v1/organizations/external_keys`

List external key configs in the caller's organization.

Results are ordered by creation time (newest first). Use the
`next_page` cursor from the response to fetch subsequent pages.

## Parameters

- `limit?:optional int` (query parameter)

  Number of results per page.

  default: 20

- `page?:optional string` (query parameter)

  Opaque cursor from a previous response's `next_page`.

## Returns

- `class ExternalKey`

  - `"external_key" type`

  - `string id`

    Identifier of the external key config. A tagged ID prefixed `ekey_`, or — for organizations on the Claude Platform on AWS — the AWS KMS key ARN.

  - `Attachment attachment`

    Whether any workspace uses this config to encrypt its data — counting live and archived workspaces (an archived workspace's data remains encrypted under the config), excluding deleted ones. Only an attached config is used by the encryption path; an `unattached` config is inert and can be deleted.

  - `\Datetime createdAt`

  - `?string displayName`

    Human-friendly display name. Null if none was set.

  - `string geo`

    Data residency geo. Selects which regional validator handles this key's encrypt/decrypt roundtrips.

  - `ProviderConfig providerConfig`

    KMS provider identity and auth coordinates.

  - `\Datetime updatedAt`

## Example

```php
<?php

require_once dirname(__DIR__) . '/vendor/autoload.php';

use Anthropic\Client;

$client = new Client(apiKey: 'my-anthropic-api-key');

$page = $client->organization->externalKeys->list(limit: 1, page: 'page');

var_dump($page);
```
