Batching with Google Places: Is it possible? - google-maps-api-3

Question

I was wondering if it's possible to send batched requests to maps.googleapis.com. As far as I can tell, it isn't.
I was using the Google API Client Library with supports batching, but it's only for www.googleapis.com. I went ahead and hacked it so that I could call the Places API, and it worked fine for normal calls, but when I actually tried to batch them, I got a 404 error:
"The requested URL /batch was not found on this server. That’s all we know."
So it appears that maps.googleapis.com does not support batching, but I wanted to be sure this is true. If anyone knows otherwise, please tell me how. Thanks!
inside google-api-php-client/src/Google/Config.php:
- 'base_path' => 'https://www.googleapis.com',
+ 'base_path' => 'https://maps.googleapis.com',
google-api-php-client/src/Google/Service/Maps.php:
(I added this file to make Places calls possible.)
<?php

foreach($inputs as $input) {
$req = $service->places->autocomplete($input, 37.7833, -122.4167, 500);
$batch->add($req, $input);
}
$results = $batch->execute();
print_r($results);
print_r($req);
