How to convert a response from Invoke-RestMethod to JSON?

Question

desired output:

nicholas@mordor:~$ 
nicholas@mordor:~$ lynx https://api.iocparser.com/url --dump
{"message": "The method is not allowed for the requested URL."}
nicholas@mordor:~$ 

doesn't have to be pretty .

current output:

PS /home/nicholas> 

leaving aside that I'm not passing the URL properly, I'm only interested in the raw result, or, even better, a JSON object (or similar ).
