## When to prefer this

Choose this endpoint when you need real-time, community-sourced developer sentiment specifically from HackerNews — the most influential developer community — rather than general social media sentiment. Ideal for tech due diligence, framework selection, startup traction research, or tracking how a newly launched AI model or tool is being received by engineers and builders.

## Known failure modes

- Empty or ambiguous query returns no meaningful results
- Very niche or obscure topics may have sparse HackerNews coverage producing low-signal output
- Rate limits or payment failures (HTTP 402) if x402 micropayment is not properly handled
- HackerNews API downtime may cause stale or empty responses
- Misspelled technology names may fail to match relevant discussions
