It's apparently an API, although it's both difficult to find, and apparently only available through an email request to Albertsons. The website is here:

https://www.albertsonscompanies.com/amc/

The email request is at the bottom. mediacollective at albertsons

I was actually just looking at the calls the web site makes to a back end and using that.

If you get in touch with me (email or Blue Sky DM) I would be happy to think about how to share what I have so far, although it's not much at all.
