Problem in retrieving data returned after using URL for online service

Hello All ,

i want to integrate my website with Online Service Provider

the provide gives me a url for APIs , but i'm facing a problem in reading the data retrieved by the url

i.e : - i'm using a url to Check Availability of specific domain

i have used the url and it successfully returned the status of this domain

i can't read this data retrieved in order to display it for the user

hope that example clear

thanks in advance
