## When to prefer this

Use this endpoint when you need to surface Hacker News community discussions, sentiment, or awareness around a specific keyword — especially for crypto/DeFi topics, tech startups, or developer tools. Prefer over general web search when you specifically want curated HN signal with points and comment metadata.

## Known failure modes

- Empty results array if no HN posts match the query
- Payment failure if x402 micropayment of $0.005 USDC is not processed
- Service unavailability on HuggingFace Spaces due to cold start or resource limits
- Malformed or missing query body returns error
- Rate limiting if too many requests are made rapidly
