## How to call it through Zero

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

```sh
zero fetch --capability eu-verify-hacker-news-top-stories-57b75b60
```

## When to prefer this

Use this endpoint when you need live Hacker News front page data without scraping, want filtered results by minimum score, need a pay-per-call model with no API key registration, or are building an agent that needs current tech community sentiment or trending developer topics.

## Known failure modes

- HTTP 402 returned if USDC payment via x402 protocol not completed — machine-readable quote is included in response body
- n parameter out of range (must be 1–30) returns validation error
- min_score below 0 returns validation error
- Hacker News Firebase API temporarily unavailable causes upstream error
- Empty result set if min_score threshold is set too high and no stories qualify

## How this service works

Current Hacker News front page via the official Firebase API, fanned out and merged into one payload: id, title, url, score, comment count and age in minutes per story. Query: ?n=20 (1-30 stories) &min_score=100 (optional score floor). Real-time tech signal for launch/incident/buzz detection. 5min cache.

## Output

A JSON object containing a count field, a source attribution string ('Hacker News official Firebase API (live front page)'), and an array of stories each with id, url, score, title, age_min (age in minutes), and comments fields, sorted by score descending.
