除了通過ECS控制台或售賣頁進行雲端服務器續約外，阿里雲還支援直接通過API進行續約查詢和續約管理。
背景資訊
對於訂用帳戶的雲端服務器，生命週期非常重要。如果雲端服務器資源不能按時續約，將可能導致伺服器被鎖定甚至被釋放，從而影響業務持久性。API協助您及時瞭解和檢查資源的到期時間，並完成續約儲值功能。

查詢執行個體列表的API，通過過濾參數，您可以查詢一定時間範圍內到期的執行個體資訊。通過設定過濾參數ExpiredStartTime和ExpiredEndTime（時間參數按照ISO8601標準表示，並需要使用UTC時間。 格式為：yyyy-MM-ddTHH:mmZ） ，可以方便地查詢該時間範圍內到期的執行個體列表。如果需要通過安全性群組進行過濾，只需加上安全性群組ID即可。

續約執行個體只支援訂用帳戶的伺服器類型，不支援隨用隨付的伺服器，同時要求使用者必須支援帳號的餘額支付或信用支付。執行API的時候將執行同步的計費和訂單產生。因此，執行API的時候必須保證您的帳號有足夠的資金支援自動計費。
def _renew_instance_action(instance_id, period='1'):
request = RenewInstanceRequest()
request.set_Period(period)
request.set_InstanceId(instance_id)
response = _send_request(request)
logging.info('renew %s ready, output is %s ', instance_id, response)續約執行個體將會自動完成計費。在完成續約後，您可以根據InstanceId查詢執行個體的資源到期時間。由於API為非同步任務，查詢資源到期時間可能需要延遲10秒才會變化。
開啟雲端服務器自動續約
為了減少您的資源到期維護成本，針對訂用帳戶的ECS執行個體，阿里雲還推出了自動續約功能。 自動續約扣款日為伺服器到期前第9天的08:00:00。如果前一日執行自動計費失敗，將會繼續下一日定時執行，直到完成計費或者9天后到期資源鎖定。您只需要保證自己的帳號餘額或者信用額度充足即可。
查詢自動續約設定
您可以通過OpenAPI來查詢和設定自動續約。該API僅支援訂用帳戶的執行個體，隨用隨付的執行個體執行將會報錯。查詢執行個體的自動續約狀態支援一次最多查詢100個訂用帳戶的執行個體，多個執行個體ID以逗號串連。
DescribeInstanceAutoRenewAttribute的入參為執行個體ID。
InstanceId：支援最多查詢100個訂用帳戶的執行個體，多個執行個體ID以逗號串連。
def describe_instance_auto_renew_setting(instance_ids, expected_auto_renew=True): describe_request = DescribeInstanceAutoRenewAttributeRequest() describe_request.set_InstanceId(instance_ids) response_detail = _send_request(request=describe_request) failed_instance_ids = '' if response_detail is not None: attributes = response_detail.get('InstanceRenewAttributes').get('InstanceRenewAttribute') if attributes: for item in attributes: auto_renew_status = item.get('AutoRenewEnabled') if auto_renew_status != expected_auto_renew: failed_instance_ids += item.get('InstanceId') + ',' describe_instance_auto_renew_setting('i-bp1aet7s13lfpjop****,i-bp13uh1twnfv7vp8****')返回樣本如下：
{"InstanceRenewAttributes":{"InstanceRenewAttribute":[{"Duration":0,"InstanceId":"i-1111","AutoRenewEnabled":false},{"Duration":0,"InstanceId":"i-2222","AutoRenewEnabled":false}]},"RequestId":"71FBB7A5-C793-4A0D-B17E-D6Bxxxxxxxxx"}如果設定自動續約，則返回的屬性AutoRenewEnabled為true，否則返回false。
設定和取消雲端服務器的自動續約
設定自動續約有三個入參：
InstanceId：支援最多查詢100個訂用帳戶的執行個體，多個執行個體ID以逗號串連。
Duration：支援1、2、3、6、12，單位為月。
AutoRenew：true/false， true為開啟自動續約，false為取消自動續約。
def setting_instance_auto_renew(instance_ids, auto_renew = True): logging.info('execute enable auto renew ' + instance_ids) request = ModifyInstanceAutoRenewAttributeRequest(); request.set_Duration(1); request.set_AutoRenew(auto_renew); request.set_InstanceId(instance_ids) _send_request(request)執行成功返回Response如下：
{"RequestId":"7DAC9984-AAB4-43EF-8FC7-7D7xxxxxxxxx"}續約成功後，您可以再執行一次查詢。如果續約成功將返回續約時間長度以及是否開啟自動續約。
{"InstanceRenewAttributes":{"InstanceRenewAttribute":[{"Duration":1,"InstanceId":"i-1111","AutoRenewEnabled":true},{"Duration":1,"InstanceId":"i-2222","AutoRenewEnabled":true}]},"RequestId":"7F4D14B0-D0D2-48C7-B310-B1DF713D4331"}
