Pull in ALL posts from the last two weeks using Rest API

Question

So I am working with the WordPress REST API and I would like to pull in all the posts from the last 2 weeks, so approximately 14 days.

In the WordPress REST API arguments, they have a before and after argument (https://developer.wordpress.org/rest-api/reference/posts/#example-request) that I might be able to utilize, but I'm unsure how to take this approach.

The WordPress REST API endpoint is being called using $response = wp_remote_get.

Here is my completed method to pull in ALL post for now:

public function get_posts_via_rest_api(): array
{
    $page = get_option('global_posts_page');
    if (!$page) {
        $page = 1;
    }
    try {
        $response = wp_remote_get(
            'https://example.com/wp-json/wp/v2/posts?page=' . $page
        );
        if ((!is_wp_error($response)) && (200 === wp_remote_retrieve_response_code($response))) {
            $response_body = json_decode(
                $response['body'],
                false,
                512,
                JSON_THROW_ON_ERROR
            );

            return empty($response_body) ? [] : $response_body;
        }
    } catch (Exception $e) {
        error_log(
            print_r(
                'Error: ' . $e,
                true
            )
        );

        return [];
    }
}

Use PHP's strtotime() function to retrieve the timestamp for the date fourteen days ago, then date() to cast it into an ISO 8601-compliant string which can be passed into the after parameter.

I'm using sprintf() here to insert the date just to keep things a bit cleaner and avoid a mess of concatenation.

$url = sprintf(
  'https://example.com/wp-json/wp/v2/posts?after=%s&page=%d',
  date( 'c', strtotime( '-14 days' ) ),
  $page
);
