How to improve an API call to Google

Hey!

I'm using Google APIs to retrieve a screenshot of a specific website. After getting the API response I'm creating a jpg using Image Intervention. The GET request I'm sending:

https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url={WEBSITE_LINK}&screenshot=true

and my code looks like this:

if(
(
$api_response = @file_get_contents("https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url=" . $websiteURL . "&screenshot=true")
) !== false
) {
     $result = json_decode($api_response, true);
     $screenshot1 = $result['lighthouseResult']['audits']['final-screenshot']['details']['data'];
     $screenshot = str_replace(array('_','-'),array('/','+'),$screenshot1);
     $screenshot_name = 'logos/' . $request->domain . '.jpg';
     Image::make(file_get_contents($screenshot1))->resize(120, 120)->save(public_path() . '/' . $screenshot_name);
}

But it's way too slow. Can you suggest me something to speed up this process? Do you have any idea why it takes up to 30 seconds to get a response from this GET request?
