I am looking at this article on the Gallery API in Magento2. I am testing the code samples in my browser

var api = $('[data-gallery-role="gallery"]').data('gallery');

However, this returns undefined... The first part does return an element

$('[data-gallery-role="gallery"]')

The later part is what seems to not be working as expected. Any idea what's wrong?

I figured it out. We are using a custom theme on this project, so navigating to

custom-theme-dir/Magento_Catalog/templates/product/view/gallery.phtml

I found

<script type="text/x-magento-init">
    {
        "[data-gallery-role=gallery-placeholder]": {
           ...

So in my case the code to access the fotorama api is

var fotorama = jQuery('[data-gallery-role=gallery-placeholder').data('gallery');
