To get the list of available Key resources, make a [List](list.md#List) request.

## gRPC request

**rpc Get ([GetKeyRequest](#yandex.cloud.iam.v1.GetKeyRequest)) returns ([Key](#yandex.cloud.iam.v1.Key))**

## GetKeyRequest {#yandex.cloud.iam.v1.GetKeyRequest}

```json
{
  "key_id": "string",
  "format": "KeyFormat"
}
```

#|
||Field | Description ||
|| key_id | **string**
