Example prompt: What's the live HackerNews sentiment and front-page velocity right now for 'Llama 3'? I want to see what developers are actually saying and how fast it's trending.

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment and trend velocity from HackerNews — especially for frameworks, open-source libraries, AI models, and dev-tool startups. Prefer it over generic social media sentiment APIs when the target audience is specifically developers and technical practitioners, and when front-page velocity and HackerNews ranking dynamics matter to the analysis.

## Known failure modes

- Empty or whitespace query string returns a validation error

- HackerNews API rate limits or outages may cause degraded or stale data
- Ambiguous single-character or symbol queries may yield irrelevant results
