## When to prefer this

Choose this endpoint when you need real-time developer community pulse specifically from HackerNews — the most influential tech forum for engineers, founders, and early adopters. Ideal for tracking launch buzz, competitive sentiment, or trending velocity of a technology topic among a technical audience, rather than general social media or mainstream news sentiment.

## Known failure modes

- Empty or overly broad query returns noisy or unfocused results
- Very niche or newly coined terms may return no HackerNews matches
- Rate limiting or payment failure (402) if USDC balance is insufficient
- HackerNews API outages may delay or block live data retrieval
- Misspelled or ambiguous keyword may match unintended topics
