Endpoint
POSThttps://twin.unykorn.org/research/hn-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to search Hacker News content specifically — either stories or comments — with control over sort order and recency window. It is ideal for competitive intelligence, technology trend monitoring, developer community sentiment, and tracking mentions of specific products, companies, or projects within the HN ecosystem. Prefer it over generic web search when the HN community perspective is specifically valuable.
Side effects
- Empty results if query matches nothing or date range is too narrow
- Rate limiting or payment failure if USDC balance is insufficient
- Invalid enum value for sort or type fields returns validation error
- limit exceeding 50 or since_days exceeding 3650 rejected by schema
- Query string left blank returns error (q is required)
