How can i check if a site name created

I use CLOUD FLARE API to create a site but ut i want to check if site name existed. I know if i send request create site. If it existed, CLOUD FLARE API would send a request info to me but because some reasons i want to check if it existed first.
Thanks. I send a request to : https://api.cloudflare.com/client/v4/zones?name=hoccode.com but i can’t do it.
