alt Hacker NewsYou just curl the site or use its API, if it has one? Then you store the result in a database and see if its value has flipped. I don't get the question; this is trivial.

And how exactly does it call any arbitrary API or know which site to curl for any arbitrary question a user might ask? Your answer doesn’t contemplate the how this actually works.
> YesNotice works by periodically checking the status of the item you care about (e.g., product stock, website availability, domain status) and comparing it to the previous status. When it detects a change from no to yes, it sends you a notification via email.
How does it generalize arbitrary indications of status into yes/no?
How does it know how to use arbitrary APIs to obtain arbitrary indications of status?
That's if the website you're querying is a static html file but the web is much more dynamic and varied. Some of the questions I have: does yesnotice execute js, does it handle an answer appearing on a different page, does it handle ambiguous launch language. In essence: how does it work?
what site does it check? what api does it call?
one of the examples is to see if a new coffee shop is opened in town. what's the API to call for that?
> Additionally, YesNotice will provide an estimated availability timeline for the question, so you can have some information about when to expect the change.
How is that trivial in the general case?
