For AMP (Accelerated mobile pages) pages, I know about the API to find out if a URL is cached or not. However, I'm having trouble finding one that is cached. I need to find a cached AMP URL to write/test other code against that API.
My AMP URLs don't seem to appear near the top of the search results so I'm having difficulty finding a single one which has already been cached. The only way I know is to check one by one, but maybe there something I can add to search query to find my cached pages?
Edit: I expect none or very few pages are cached already, that's why the question.
