What is the charge standard of the Baidu Online Marketing Service API

Currently, Baidu Search Marketing Services APIs are free of charge, but not without limits.

We settled the service quota to the account, which will be allocated periodically. It means you need to watch the quota and use the resources rationally.

After using out of quota, and before reallocating of quota, you will receive error message of “out of quota” while requesting, which means you can’t continue using our services.
