aiqlabs/hacker-news-link-rot

Hacker News recommends links forever and never rechecks them. Point this at the front page, or at every story above 300 points from 2013, and it reports the dead links, the redirects that answer 200 OK while the article is gone, and the domains nobody has registered - with an archived copy of each.

Broken link checker: give it a start URL, it crawls the page or whole site and returns every broken internal and external link as JSON — source page URL, broken link URL, and HTTP status code. Pay only for pages actually crawled, so cost is bounded before you run.
