## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment sourced directly from HackerNews discussions — particularly for tech topics like frameworks, AI models, dev tools, and startups. Prefer this over general social media sentiment APIs when your audience is specifically the developer/technical community and HackerNews is the relevant signal source.

## Known failure modes

- Empty or missing query string returns validation error
- Highly obscure or misspelled keywords may return no results or low-confidence sentiment
- HackerNews API downtime may cause stale or unavailable data
- Payment failure (x402) blocks the request before execution
- Rate limiting may apply for high-frequency repeated queries on the same keyword
