Historical Search Volume

‌‌ 
This endpoint will provide you with Google historical search volume, current cost-per-click, and competition values for paid search, as well as current impressions and SERP. You can get historical search volume data since the beginning of 2019, depending on keywords along with location and language combination. You can find the list of supported locations and languages here.

Datasource: DataForSEO Keyword Database
The data is based on Google Ads API. We update keyword metrics once a month after the data source completes its updates. Note that sometimes Google tends to rewrite search volume values for a given month, and we update the values in this endpoint respectively.

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

 [
		"phone",
		"watch"
	],
	"language_name" => "English",
	"location_code" => 2840
);
try {
	// POST /v3/dataforseo_labs/google/historical_search_volume/live
	$result = $client->post('/v3/dataforseo_labs/google/historical_search_volume/live', $post_array);
	print_r($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:
