## When to prefer this

Use this endpoint when you need programmatic, paid-tier access to the current Hacker News front page with filtering capabilities — ideal for agents that need reliable, structured HN data without scraping, especially when you want to threshold by point score to surface only high-signal stories.

## Known failure modes

- Upstream HN API unavailability may result in an error or stale cached response
- min_points filter set too high may return an empty array
- limit set to 0 or negative may return unexpected results
- Cached responses may be slightly behind real-time frontpage state
