Many of our data sources have limitations and quotas on how many API requests you can make in a certain period of time.
In addition to that, we've implemented a fair usage policy. The maximum number of rows that can be returned to a customer per month 100,000,000 unless stated otherwise in your contract.
The purpose of the fair usage policy is to guarantee the same level of access to the data source connectors for all customers who use it. Most Supermetrics customers will never come close to the limits outlined in the fair usage policy.
If you have any questions or concerns, please don't hesitate to contact our customer support team or reach out to your Customer Success Manager.
