Groovy Script implementation and filtering the result

Question

I have this groovy script :

def response = ["curl", "-X", "GET", "-H", "X-Auth-Key: key", "-H", "X-Auth-Email: mail", "https://api.cloudflare.com/client/v4/zones?page=1&per_page=1000"].execute().text

println $(response)

This script is working for me and its given me all the necessary information i want from Cloudflare api.

The task i want to have now is to grep the result of the command like that :

grep -Po '(?<="name":")[^"]*' | grep -v "string" | grep -v "string" | grep -v "string" | grep -v "string".

Can someone help me to integrate these grep to the result of the Groovy script ?

Thank you, Theo
