-## List External Keys
+**GET** `/v1/organizations/external_keys`
 
-**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.
 
-### Query Parameters
+## Query parameters
 
 - `limit: optional number`
 
   Number of results per page.
 
+  default: 20, maximum: 100, minimum: 1
+
 - `page: optional string`
 
   Opaque cursor from a previous response's `next_page`.
 
-### Returns
+## Returns
 
-- `data: array of object { id, attachment, created_at, 5 more }`
+- `data: array of object`
 
   - `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: object { type }  or object { type }`
+  - `attachment: object or object`
 
     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.

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

-  - `provider_config: object { kms_arn, type, region, role_arn }  or object { key_name, type }  or object { key_name, tenant_id, type, 2 more }`
+  - `provider_config: object or object or object`
 
     KMS provider identity and auth coordinates.
 
-    - `Aws object { kms_arn, type, region, role_arn }`
+    - `Aws object`
 
       - `kms_arn: string`
 
         Full ARN of the AWS KMS key.
