## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment and discussion velocity from HackerNews — particularly for evaluating frameworks, AI models, open-source libraries, or startups. Prefer this over general web sentiment tools when the target audience is specifically software developers and technically-minded builders who congregate on HackerNews.

## Known failure modes

- Obscure or very new topics may return sparse data if not yet discussed on HackerNews
- HackerNews API rate limits or downtime may cause request failures or stale data
- Ambiguous query terms (e.g. single letters or common words) may match unrelated discussions
