Error "content-type is not allowed by Access-Control-Allow-Headers in preflight Response." -API Climatempo

Question

Hello, I have a problem with CORS in the Climatempo API, my request code is this:

var api_url = '"http://apiadvisor.climatempo.com.br/api/v1/anl/synoptic/locale/BR?token=TOKEN"';   
$.ajax({
    url: api_url,
    contentType: "application/json",
    crossDomain: true,
    dataType: 'json',
    success: function(result){
        console.log(result)
    }
})

I’ve tried switching to jsonp, but also I did not succeed, I’m stuck for a long time here and everything I saw on the internet did not solve

They don’t accept the contentType: "application/json", in the configuration of Cors, in fact it is not necessary, because the contentType does not say what you expect from reply, it only states that you are sending JSON, but your request is GET and soon does not send anything, so that contentType nor should exist. Change to:

var api_url = '"http://apiadvisor.climatempo.com.br/api/v1/anl/synoptic/locale/BR?token=TOKEN"';   
$.ajax({
    url: api_url,
    crossDomain: true,
    dataType: 'json',
    success: function(result){
        console.log(result)
    }
})
