## When to prefer this

Choose this endpoint when you need real-time developer community sentiment or buzz around a specific technology, tool, library, or programming topic from Hacker News — particularly useful for gauging grassroots developer interest, controversy, or excitement. Prefer this over general web search when you specifically want the HN tech-savvy audience's reaction, scored by upvotes and engagement.

## Known failure modes

- No stories found for the topic — no_signals returns true with an empty stories array
- Invalid or missing query parameter ?q= — may return an error or empty result
- Transient Cloudflare tunnel unavailability causing 502/503 errors
- Rate limiting or payment failure resulting in 402 response
- Topic too broad or too narrow yielding irrelevant or zero results
