Will it cost money?

I am wanting to use the Admin SDK API  and Google Calendar API for integration with our bespoke CRM

It will be very light usage, probably less that 100 calls per day

I cannot work out if this will cost money, it is for a not for profit organisation so don't want to go ahead if it will be expensive.

Hopefully someone from Google will chime in but it should all be usage based and prevent you from using for a time window if usage is exceeded like their search API? Here is a good write up on the calendar API.

Make sure and wait for validation though as I have never used the calendar API myself. Just basing my statement on docs and other users past posts. 1,000,000 queries per day is the supposed limit for the calendar according to the above linked user blog.
