While prices can vary slightly by region, a typical pay-as-you-go rate for the Hot tier is **$0.055 per 10,000 operations**.<br /> <br /> Since you are only performing 200 operations, you fall into the very first pricing block. The total cost for the entire `rclone size` command would be less than a penny.<br /> <br /> **Bottom Line:** While not technically free, the monetary cost is negligible. The main &quot;cost&quot; you'll notice is the time it takes for `rclone` to complete the 200 sequential API calls.</div>
