title: Data hacker news API
description: This tool reads live information from Hacker News, a popular website where people share and discuss technology news. You can either ask for a current list of stories (like the Top, New, Best, Ask, Show, or Job lists) or ask for every story, job posting, and poll that was posted on one specific calendar day in the past. You can also choose to pull in the discussion comments underneath each story, including nested replies several levels deep.

x-guidance: 'Call this when you need Hacker News content: either a current ranked list (top, new, best, ask, show, job) or every story/job/poll posted on a given UTC date. Set ''date'' to switch to date mode; leave it empty to use category mode. Use ''reply_depth'' and ''comment_limit'' sparingly since higher values take longer. For date mode, if ''range_complete'' is false in the response, call again passing the returned ''next_page_token'' as ''page_token'' to continue scanning the same day.'
