Limits on API Gateway products and business.

Restrictions Description
User restrictions on activating the API Gateway service. To activate the service, you must complete the real-name registration.
Restrictions on the number of API groups created by a user. Each account can have at most 100 API groups.
Restrictions on the number of APIs created by a user. At most 1000 APIs can be created in each API group. That is, at most 100,000 (100 * 1000) APIs can be created in each account.
Restrictions on the number of independent domain names bound to an API group. At most five independent domain names can be bound to a group.
The limit of the official subdomain. When the API group is created successfully, the API gateway issues a secondary domain name for that group. You can test the API in the group by accessing the domain name, and the gateway restricts the number of visits to 1000 times per day. Please do not use the secondary domain name to provide API service directly.
Restrictions on parameter size. The parameters of the body location (including Form and Form other forms) cannot exceed 2 Mb, and other locations (including Header and Query) cannot exceed 128 Kb.
