**Eventual consistency**: The AWS KMS API follows an eventual consistency model. For more information, see [AWS KMS eventual consistency](https://docs.aws.amazon.com/kms/latest/developerguide/accessing-kms.html#programming-eventual-consistency).
## Request Syntax
```
{
"Limit": number,
"Marker": "string"
}
```
## Request Parameters
For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).
The request accepts the following data in JSON format.
**Note**
In the following list, the required parameters are described first.
** [Limit](#API_ListKeys_RequestSyntax) **
Use this parameter to specify the maximum number of items to return. When this value is present, AWS KMS does not return more than the specified number of items, but it might return fewer.
This value is optional. If you include a value, it must be between 1 and 1000, inclusive. If you do not include a value, it defaults to 100.
Type: Integer
Valid Range: Minimum value of 1. Maximum value of 1000.
Required: No
** [Marker](#API_ListKeys_RequestSyntax) **
Use this parameter in a subsequent request after you receive a response with truncated results. Set it to the value of `NextMarker` from the truncated response you just received.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 1024.
Pattern: `[\u0020-\u00FF]*`
Required: No
## Response Syntax
```
{
"Keys": [
{
"KeyArn": "string",
"KeyId": "string"
}
],
"NextMarker": "string",
"Truncated": boolean
}
```
## Response Elements
If the action is successful, the service sends back an HTTP 200 response.
The following data is returned in JSON format by the service.
** [Keys](#API_ListKeys_ResponseSyntax) **
A list of KMS keys.
Type: Array of [KeyListEntry](API_KeyListEntry.md) objects
** [NextMarker](#API_ListKeys_ResponseSyntax) **
When `Truncated` is true, this element is present and contains the value to use for the `Marker` parameter in a subsequent request.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 1024.
Pattern: `[\u0020-\u00FF]*`
** [Truncated](#API_ListKeys_ResponseSyntax) **
A flag that indicates whether there are more items in the list. When this value is true, the list in this response is truncated. To get more items, pass the value of the `NextMarker` element in this response to the `Marker` parameter in a subsequent request.
Type: Boolean
## Errors
For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md).
** DependencyTimeoutException **
The system timed out while trying to fulfill the request. You can retry the request.
HTTP Status Code: 500
** InvalidMarkerException **
The request was rejected because the marker that specifies where pagination should next begin is not valid.
HTTP Status Code: 400
** KMSInternalException **
The request was rejected because an internal exception occurred. The request can be retried.
HTTP Status Code: 500
