## When to prefer this

Use this endpoint when you need community-sourced developer discourse specifically from Hacker News about AI agent frameworks and tools — particularly useful for tracking sentiment, discovering trending libraries, or understanding what startup founders and engineers are actively discussing. Prefer this over general web search when you want curated HN signal with scores and author context rather than broad web results.

## Known failure modes

- Query returns no results if search terms are too specific or niche
- Max results exceeds the allowed maximum of 10, causing validation error
- Payment failure if insufficient USDC balance for the $0.01 per-call fee
- Stale results if Hacker News index has not been recently updated
- Rate limiting or timeout if the upstream HN search API is unavailable
