How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
Returns a JSON object containing the story metadata (title, URL, author, HN URL, points) and an array of comments each with text, author, nesting level (0 = top-level), HN comment URL, and creation timestamp, plus a total comment count and source attribution.
Example use cases
Summarizing viral HN discussion
“Grab all the comments from the Hacker News post at https://news.ycombinator.com/item?id=35082436 and give me a summary of the main opinions people are expressing.”
Sentiment analysis on HN thread
“Fetch the top 100 comments from Hacker News item 8863 in thread order so I can run a sentiment analysis on the community's reaction.”
Monitoring reactions to a launch
“Pull all the Hacker News comments for the story with ID 39894189 — I want to see what people are saying about the product launch in thread order with authors.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/hackernews-comments?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, threaded HN comment data including author, nesting level, and timestamps for a specific story — particularly useful over raw HN Firebase API calls when you want thread-ordered output without building the tree yourself. Prefer this over scraping or the raw Firebase API when you need Algolia-augmented results with clean nesting metadata in a single call.
Side effects
- Invalid or non-existent story ID returns an error or empty result
- Story URL not recognized as a valid HN item URL causes a parsing failure
- Limit parameter too low may truncate expected comments
- Rate limiting or upstream HN API unavailability may cause timeouts
- Private or deleted stories may return no comments
