Example prompt: Search Hacker News for discussions about the adoption of Supabase as an open-source backend — show me up to 8 results with titles, scores, authors, and links.

## When to prefer this

Use this endpoint when you need to surface community sentiment, reactions, and discussions from the Hacker News developer audience specifically about open-source project releases and adoption — particularly when you want scored, timestamped story metadata rather than raw web search results. Prefer this over general web search when your target audience is the builder/hacker community and you care about HN-specific signals like vote scores and discussion authors.

## Known failure modes

- No results returned when query terms are too niche or misspelled
- Result set capped at 10 even if more HN stories exist
- Stale or cached results if Hacker News indexing is delayed
- Payment failure or 402 response if USDC balance is insufficient
- Irrelevant results if the default query is used without a focused search term
