How this service works
Trending keywords across current Hacker News stories: terms ranked by how many titles use them, with example titles.
Output
A JSON object containing a timestamp, the list type analyzed, number of titles analyzed, and an array of trending terms each with: the keyword, share percentage of titles it appears in, count of titles containing it, a total relevance score, and example HN story titles that use the term. Also includes a plain-language summary and any degraded-mode warnings.

Technical details
Endpoint
GEThttps://hacker-news.x402tookit.com/hn-trending-topics?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, keyword-level pulse of what topics are currently popular on Hacker News without reading individual stories. Ideal for trend monitoring, content planning, or competitive intelligence where you want the signal distilled from multiple HN stories at once. Prefer this over the search endpoint when you don't have a specific query in mind and want open-ended discovery of what's trending now.
Side effects
- HN API unavailability causes degraded mode with partial results or null data
- Requesting more than 20 terms or more than 15 stories returns a validation error
- Invalid list type value causes an error — must be top, new, best, ask, or show
- Very few stories available may reduce the meaningfulness of term frequency rankings
