Indeed but I was thinking of endpoints that have remained relatively static because they have been auto generated or a history of scraping. Some Linux distros have pages like that (even if it's just a mirror list).

But my preferred solution would be using whatever endpoint the respective platform uses for notifying their users of updates.

This strikes me as a solved problem but even if you can't find a ready to use API then I'd probably sign up to a few mailing lists, update my own endpoint manually and offer 3rd party access for a modest subscription.

Either way, scraping an encyclopedia for an English phrase to parse strikes me as the worst of all the possible solutions.
