I love this idea and think there's a good chance I'll use it in the future. Generally I use followthatpage.com for getting notified of changes on a few simple pages. However, one idea that would be a pretty good use case of your tool is to get notified of new search results for any query on OpenLibrary.org . For example, if I wanted to be notified if there are any new books added to OpenLibrary that mention "hackerNews" I could use this search https://openlibrary.org/search/inside?q=hackernews https://openlibrary.org/search/inside?q=hackernews with this api call https://openlibrary.org/search/inside.json?q=hackernews https://openlibrary.org/search/inside.json?q=hackernews I probably won't build this now but if someone does please let me know.
