How this service works
Summarise a Hacker News item and its comment tree: comment count, depth, authors and top comments, truncated.
Output
Returns a structured summary of the HN item including: title, URL, domain, author, points, post timestamp, total comment count, top-level comment count, unique commenter count, maximum comment tree depth, an AI-generated summary of the story, a discussion summary, and an array of top-comment excerpts (each with author, timestamp, reply count, and text excerpt). May include a degraded flag if data retrieval was partial.
Example use cases
Digest a viral HN thread
“There's a big discussion happening on Hacker News — item ID 37592013. Can you summarize the story and pull out the top 7 comments so I can quickly understand what the community is saying without reading everything?”
Research community reaction to a product launch
“Our product just got submitted to Hacker News as item 39041234. Can you give me a summary of the post and show me the most-upvoted comments so I can gauge how developers are reacting?”
Monitor depth of a technical debate
“I want to know how deep and active the conversation is on Hacker News item 40123456 — how many comments are there, how many unique people chimed in, and what are the top 3 comments saying?”

Endpoint
GEThttps://hacker-news.x402tookit.com/hn-item?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a summarized digest of a specific Hacker News story and its discussion — identified by item ID — rather than searching for stories or browsing feeds. Ideal when you already have a HN item ID (from a URL like news.ycombinator.com/item?id=8863) and want both story metadata and community sentiment without reading the full thread. Prefer this over the search or feed endpoints when the target item is already known.
Side effects
- Invalid or non-existent item ID returns null or error fields
- Deleted or dead items may return minimal metadata with empty comment data
- Very large comment trees may be truncated, indicated by the degraded flag
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting if too many requests are made in quick succession
- The 'top' parameter outside 0-10 range may be rejected or clamped
