API Management rates are calculated from the total number of API request.
You can check the total number of API request in the following steps.
Here is example which checks the total number of API request from Dec.28 to the last 3 months(Sep.28 9:00 am - Dec.28 9:00 am).

1. Log in to API Management.


2. Click Custom button on Dashboard page.


3. You can see a calendar of the last three months
Note:
You can't select the range of more than a month in the calendar, so you need to check in 3 parts to check data for the last three months.


4. Click date in the order of start date(Nov.29), end date(Dec.28) to check data for the last month.
Note:
API Management displays the data from the day before the start date which you selected, so click Nov.29 which is the following day of Nov.28 in this case.


5. In TOTAL TRAFFIC you can see the total number of API request from Nov.28 9:00 am to Dec.28 9:00 am.


6. Repeat the above steps on the period from 2 months ago(Oct.28-Nov.28) and on the period from 3 month ago(Sep.28-Oct.28).
With three month data included, you can get the total number of API request for 3 months.
Note:
If you select the range of less than 9 days in the calendar, the scale on graph changes from day to hour and start time changes from 9:00 am to 0:00 am.
by day(select the range of more than 9 days in the calendar): Nov.28 9:00 am - Dec.28 9:00 am by hour(select the range of less than 9 days): Dec.25 0:00 am - Dec.28 11:00 pm
Even if you select the range of less than 9 days, you can change start date from 0:00 am to 9:00 am by selecting By Day.

Monthly fixed charge is stopped at the time of requesting the cancelation of service. So it won't incur fixed charge of the next month.

It is about the different number of API calls included in monthly fixed charge and contract period. The analytics function is also different.
