# List External Keys

`$ ant organization:external-keys list`

**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 number` (query parameter)

  Number of results per page.

  minimum: 1, maximum: 100

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

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

## Returns

- `ExternalKeyListResponse: object`

  Opaque-cursor page of external keys, ordered by creation time (newest first).

  - `data: array of ExternalKey`

    - `type: "external_key"`

    - `id: string`

      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: ExternalKeyAttachedAttachment or ExternalKeyUnattachedAttachment`

      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.

      - `external_key_attached_attachment: object`

        - `type: "attached"`

      - `external_key_unattached_attachment: object`

        - `type: "unattached"`

    - `created_at: string`

      format: date-time

    - `display_name: string`

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

    - `geo: string`

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

    - `provider_config: AWSExternalKeyConfig or GCPExternalKeyConfig or AzureExternalKeyConfig`

      KMS provider identity and auth coordinates.

      - `aws_external_key_config: object`

        - `type: "aws"`

        - `kms_arn: string`

          Full ARN of the AWS KMS key. On Claude Platform on AWS the key must be a single-Region key in your organization's own AWS account; cross-account keys, multi-Region keys, and alias ARNs are rejected.

          maxLength: 2048

        - `region: optional string`

          AWS region. Derived from `kms_arn` if omitted.

      - `gcp_external_key_config: object`

        - `type: "gcp"`

        - `key_name: string`

          Full resource name of the Cloud KMS key.

      - `azure_external_key_config: object`

        - `type: "azure"`

        - `key_name: string`

          Name of the key within the vault.

        - `tenant_id: string`

          Azure AD tenant ID.

        - `vault_uri: string`

          Key Vault data-plane URI — `https://{vault-name}.vault.azure.net` or `https://{hsm-name}.managedhsm.azure.net`.

        - `client_id: optional string`

          Azure AD application (client) ID. Omit to use Anthropic's multitenant app. Provide only if using a single-tenant app registration in the customer's directory.

    - `updated_at: string`

      format: date-time

  - `next_page: string`

    Opaque cursor for the next page, or null if no more results. Pass as `?page=` to fetch the next page.

```bash
ant organization:external-keys list \
  --api-key my-anthropic-api-key
