API Request Error

Hello, I am trying to do an API request to Cloudflare. The API request is to fetch the :zone_identifier:

curl -X POST "https://api.Cloudflare.com/client/v4/zones" \
     -H "X-Auth-Email: [My Email]" \
     -H "X-Auth-Key: [Global API Key]" \
     -H "Content-Type: application/json"

I am getting however the following response:
{"success":false,"errors":[{"code":1002,"message":"Invalid domain"}],"messages":[],"result":null}

What does invalid domain error means and why is it thrown? Can’t find much information about it. Thank you!

That request probably should be GET instead.
