This is the way to find discount price percentage by product id:

        require_once('./config/config.inc.php');

        require_once('init.php');

        $context = \Context::getContext();

 

         $product=new Product($params['id_product'], false, $context->language->id);

        $id_customer = (isset($context->customer) ? (int)$context->customer->id : 0);

        $id_group = (isset($tcontext->customer) ? $tcontext->customer->id_default_group : _PS_DEFAULT_CUSTOMER_GROUP_);

        $id_country = (int)$id_customer ? Customer::getCurrentCountry($id_customer) : Configuration::get('PS_COUNTRY_DEFAULT');

        $id_currency = (int)$context->cookie->id_currency;

        $id_shop = (int)$context->shop->id;

$quantity_discounts = SpecificPrice::getQuantityDiscounts($product->id, $id_shop, $id_currency, $id_country, $id_group, null, true,$id_customer);
