Restrictions on Usage
Craft does not put restrictions on the number of API calls you can do in a 30-day period. However, we do recommend not perform more than 10 requests per second to the Alerts API. The Alerts API speed varies from request to request, depending on the depth of data requested for the query as well as the complexity of the specified filters.
Please, contact us at [email protected] if Alerts API missing any functionality required for your use case.
