## When to prefer this

Choose this endpoint when you need to quickly surface Hacker News community discussions for product discovery, founder sentiment, or user research purposes without scraping HN manually. It is ideal for startup founders and product teams who want structured, scored story data from HN filtered to a specific topic. Prefer this over general web search when the target audience is specifically the HN/tech-founder community.

## Known failure modes

- No results returned if the query is too niche or uses obscure terminology not present in HN story titles
- Max results capped at 10; requests for more will be silently truncated
- Stale or cached results if the underlying HN data is not real-time
- Payment failure (x402) if USDC balance is insufficient
- Query too generic may return unrelated HN stories with low relevance
