## How to call it through Zero

```

## When to prefer this

Use this endpoint when you need a quick, paid-API-gated snapshot of the current Hacker News front page without scraping HN directly. Prefer this over raw HN API calls when your agent already operates in a micropayment (x402) context and you want a clean, normalized response without handling HN's multi-step item-fetching pattern.

## Known failure modes

- HN API unreachable or rate-limited — returns upstream error
- Invalid limit parameter type — returns validation error
- Tailscale node offline — connection refused
- Empty response if HN top list temporarily unavailable
