I tried to show NYtimes bestseller API’s JSON data.

Here is the JSON

Here’s my PHP code so far and It is working to retrive data from books array.

    $requestNY = wp_remote_get( 'https://api.nytimes.com/svc/books/v3/lists/current/hardcover-fiction.json?api-key=xxx' );
    $bodyNY = wp_remote_retrieve_body( $requestNY );

    $dataNY = json_decode( $bodyNY );
    if( ! empty( $dataNY ) ) {

echo '<ul>';
foreach( $dataNY->results->books as $result ) {
    
    echo '<li>';
    
    echo "$result->title by $result->author" ;
    echo '<br/> Amazon link: ';
    echo '<a href="' . esc_url( $result->amazon_product_url ) . '">' . $result->amazon_product_url . '</a>';
    echo'<img src="'.$result->book_image.'" width="150">';
    echo '</li>';
} 

echo $dataNY->copyright;

echo '</ul>';
    }

Now I want to access isbns and buy_links data. How to do that?
