Example prompt: What's the live HackerNews sentiment and front-page velocity for 'Cursor IDE' right now — are developers excited or skeptical about it?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the gold standard for early-adopter and technical audience opinion. Prefer this over general social media sentiment tools when your target audience is software engineers, startup founders, or AI researchers, and you need front-page velocity alongside qualitative discussion signals rather than Twitter/Reddit-style volume metrics.

## Known failure modes

- Empty or missing query parameter returns a validation error
- Very obscure or misspelled keyword may return no results or sparse data
- Rate limiting or payment failure (HTTP 402) if USDC payment is not properly attached
- HackerNews API downtime may cause stale or unavailable data
- Generic single-character or stop-word queries may return irrelevant results
