Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

## When to prefer this

Choose this endpoint when you specifically need to search Hacker News — the primary tech-savvy developer and startup community — for stories, discussions, and community reactions. Prefer it over generic web search when you want engagement signals (points, comments) or direct links to HN discussion threads. Use the multi-source sibling endpoint if you also want Wikipedia or academic results alongside HN.

## Known failure modes

- Query exceeds 200 characters — request rejected
- Limit parameter outside 1–10 range — validation error
- No results found for obscure or very recent queries
- Service degraded flag set true when upstream HN search is partially unavailable
- Missing required 'q' parameter returns error
