Number of API Calls Consumed while Using messaging Service

Messaging Service
1

Will the data Size in API Request Sent from the Client Part in case of Publish vary upon the Number of followers in a Channel to be published , or is it a 1 Time API Call Operation ?

If I Send One 'Publish ’ API Request to a Channel which has 1000 Subscriber, How much API call does it makes 1 , or 1000 ?
