DESCRIPTION
Topic trend brief API to check whether interest in a topic is rising: send a topic and window, get back Wikipedia pageview trend, recent news mention volume, Hacker News mention volume, and X/Twitter mention volume in one call. Built for agents asking 'is this topic trending' or 'rising topic' without polling four separate signal sources by hand. Composite: one call runs wikipedia-pageviews + news-search + hn-search + x-search in parallel and reports interest over time plus a rising/flat verdict. hn-search is the required leg; wikipedia-pageviews (needs a matching article title), news-search, and x-search (needs an X bearer token configured) degrade the brief instead of failing the call when their upstream can't answer. Use it as a topic trend API, rising-topic detector, or mention-volume tracker for research and market-scouting agents.
