API request Google Apps Scripts

Question

I need to request information from api.I tried to make a request with UrlFetchApp.fetch and fetchAll.In both cases i got nothing.Here s my code:

  var request1 = {
   url: "https://seo-fast-audit.p.rapidapi.com/?url=" + url,
   method : 'GET',
   params: {url: 'https://docteurseo.fr/'}, 
   headers: {
         "x-rapidapi-host": "seo-fast-audit.p.rapidapi.com",
         "x-rapidapi-key": "KEY"
            }
};
let response = UrlFetchApp.fetchAll([request1])

(here i replaced key)

So what is my problem?Is that problem in async functions or am i requesting not correctly?

Here s API i am using https://rapidapi.com/DocteurSEO/api/seo-fast-audit
