How can developers effectively filter out marketplace prices and display only Amazon prices when using PHP scripts to fetch data from Amazon's API?

To filter out marketplace prices and display only Amazon prices when using PHP scripts to fetch data from Amazon's API, developers can check the "IsFulfilledByAmazon" attribute in the API response. If this attribute is true, then the price is sold by Amazon directly. By filtering out prices based on this attribute, developers can display only Amazon prices to users.

// Assuming $amazonApiResponse contains the API response data
$amazonPrices = array_filter($amazonApiResponse['prices'], function($price) {
    return $price['IsFulfilledByAmazon'] === true;
});

foreach($amazonPrices as $amazonPrice) {
    echo "Amazon Price: " . $amazonPrice['Price'] . "<br>";
}
