Example prompt: Search Hacker News for discussions about the open-source project releases and adoption of 'Ollama' and return up to 8 results including their titles, links, scores, and timestamps.

## When to prefer this

Choose this endpoint when you specifically need Hacker News community signals — upvotes, authors, timestamps — about open-source project releases and adoption, rather than broader web search results or GitHub metrics. It is ideal for gauging developer sentiment and community engagement around OSS projects in a focused, structured way.

## Known failure modes

- No results found if the query term is too narrow or obscure for HN coverage
- Payment failure if USDC balance is insufficient for the $0.01 per-call fee
- Rate limiting or timeout if the underlying HN search index is slow to respond
- Stale or incomplete results if HN indexing lags behind new submissions
