Google Maps API; “CORS header ‘Access-Control-Allow-Origin’ missing” error [duplicate]

I'm trying to calculate the estimated travel time between two places, with the Google Maps API. I am asking for the data in the following way:

const Url = ',-80.259947&destinations=25.768915,-80.254659&key=' + API_KEY;
try {
  const response = await fetch(Url);
  const data = await response.json();
} catch(e){

The problem is that in the browser console I get the error:

TypeError: NetworkError when attempting to fetch resource

and it also shows me a warning:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at,-80.259947&destinations=25.768915,-80.254659&key=API_KEY. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

But when I look at the console in the network part it shows me that the call was completed successfully and it shows me the following json:

   "destination_addresses" : [ "3670 SW 3rd St, Miami, FL 33135, USA" ],
   "origin_addresses" : [ "3911 SW 2nd Terrace, Coral Gables, FL 33134, USA" ],
   "rows" : [
         "elements" : [
               "distance" : {
                  "text" : "0.9 km",
                  "value" : 881
               "duration" : {
                  "text" : "2 mins",
                  "value" : 144
               "status" : "OK"
   "status" : "OK"

Can someone help me solve this problem? I have tried similar questions on the site but I have not been able to solve the problem. Thanks in advance.



You are using Distance Matrix Service on client side. But the manner you trying to access the API is not supported for client(browser)-site and it will not work reliably.

Good that there is a library for your use-case: Here's the guide for the Distance Matrix Service on client side. And here's a vanilla-js example Check it out.

Maybe this snippet will help you:

const matrix = new google.maps.DistanceMatrixService();

  origins: [new google.maps.LatLng(25.7694708, -80.259947)],
  destinations: [new google.maps.LatLng(25.768915, -80.254659)],
  travelMode: google.maps.TravelMode.DRIVING,
}, function(response, status) {
  //do something
