Example prompt: What's the current HackerNews sentiment and front-page velocity around 'Llama 3' right now — are developers excited or skeptical about it?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment from HackerNews specifically — ideal for tracking technology adoption signals, startup reputation, AI model reception, or framework popularity among technical audiences. Prefer this over general web sentiment tools when you care specifically about the HackerNews developer demographic and want velocity/trending data alongside sentiment.

## Known failure modes

- Empty or overly broad query returns low-signal or noisy results
- Very niche or misspelled keyword returns no matching HackerNews discussions
- HackerNews API rate limits or downtime cause delayed or missing data
- Generic term queries (e.g. 'AI') return unfocused aggregate data with low actionability
- Payment failure via x402 prevents endpoint access
