## When to prefer this

Choose this endpoint when you need sentiment specifically from the Hacker News / developer and tech enthusiast community, rather than general social media or Twitter sentiment. Ideal for evaluating how technical audiences perceive a technology, framework, startup, or product — especially useful for B2D (business-to-developer) products, open source projects, or technology decisions where HN community opinion is a leading signal.

## Known failure modes

- Empty or very niche query returns insufficient HN data for reliable sentiment
- Query too broad returns noisy or ambiguous sentiment signal
- Rate limiting or payment failure returns 402 if micropayment is not processed
- Malformed query parameter returns 400 bad request
- Topic with no recent HN coverage may return low-confidence results
