OnPage API Pages By Resource

‌‌
This endpoint will return the list of pages where a specific resource is located. Using this function you will also get the data related to the pages that contain a specified resource.
You can get the URL of a resource using the Resources endpoint.

Instead of ‘login’ and ‘password’ use your credentials from https://app.dataforseo.com/api-dashboard

<?php
// You can download this file from here https://cdn.dataforseo.com/v3/examples/php/php_RestClient.zip
require('RestClient.php');
$api_url = 'https://api.dataforseo.com/';
// Instead of 'login' and 'password' use your credentials from https://app.dataforseo.com/api-dashboard
$client = new RestClient($api_url, null, 'login', 'password');

$post_array = array();
// simple way to get a result
$post_array[] = array(
   "id" => "02241700-1535-0216-0000-034137259bc1",
   "url" => "https://www.etsy.com/about/jobs.workco2018.js?"
);
try {
   // POST /v3/on_page/pages_by_resource
   // the full list of possible parameters is available in documentation
   $result = $client->post('/v3/on_page/pages_by_resource', $post_array);
   print_r($result);
   // do something with post result
} catch (RestClientException $e) {
   echo "\n";
   print "HTTP code: {$e->getHttpCode()}\n";
   print "Error code: {$e->getCode()}\n";
   print "Message: {$e->getMessage()}\n";
   print  $e->getTraceAsString();
   echo "\n";
}
$client = null;
?>

The above command returns JSON structured like this:
