## How to call it through Zero

```sh
zero fetch --capability sitesignal-hacker-news-trending-70d8b681
```

Example prompt: Pull the top 15 stories from Hacker News right now — I want each one's rank, score, comment count, and a link to the original source.

## When to prefer this

Choose this endpoint when you need a quick, structured snapshot of current Hacker News front-page stories with enriched metadata (score, comments, timestamps, links) in a single call — especially useful for newsletters, developer dashboards, or agent briefings that need ranked tech news with source attribution, without scraping HN directly.

## Known failure modes

- Hacker News API unavailable or rate-limited — upstream fetch fails
- limit parameter out of range (must be 1–20) — validation error
- Cloudflare tunnel instability causing intermittent 502/503 responses
- Stale data if upstream HN API is slow to reflect new rankings

## Output
