## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment and discussion velocity from HackerNews — particularly useful for gauging how technical audiences perceive a startup, framework, AI model, or library right now, as opposed to general social media sentiment or static survey data

## Known failure modes

- Missing or empty 'query' parameter returns validation error
- Query returns no results if keyword has no recent HackerNews activity
- Payment failure via x402 if insufficient USDC balance
- Rate limiting or timeout if HackerNews API is slow or unavailable
- Ambiguous keywords may return mixed or irrelevant sentiment
