Remove all contacts from Sharedlist(ContactList) using Api

I want to remove all the contacts from a sharedlist using api. One of the method i found out is with rest api is to send ids of all the contacts in the list.When there are more contacts in list it takes lot of time as i have to query the list to get the contact ids first, then send PUT request with the ids to remove the contacts. Is there any alternative way to do it. If not then what is the max number of ids i can send with membership deletions options.
