QPS limit on an API operation in ApsaraVideo Live - API Reference| Alibaba Cloud Documentation Center

ApsaraVideo Live limits the queries per second (QPS) of API calls for each user. If the number of times that a user calls an API operation in a second or minute exceeds the limit, throttling is triggered. This topic describes the QPS limits on calling different API operations in ApsaraVideo Live. To prevent your service from being interrupted by throttling, we recommend that your number of API calls per second or minute be under the QPS limit.

QPS limit on calling an API operation

The QPS limit on calling an API operation indicates the maximum number of times that an Alibaba Cloud account and the RAM users that belong to this account can call the API operation per second or per minute. For example, the QPS limit on calling the AddLiveDomain operation is 30. If you have an Alibaba Cloud account and five RAM users that belong to your account, the Alibaba Cloud account and five RAM users all together can call the AddLiveDomain operation no more than 30 times per second.

Not all API operations have QPS limits. The following tables describe the QPS limits on calling different API operations.
