## How to call it through Zero

```sh
zero fetch --capability hacker-news-tech-community-brief-b8aec687
```

Example prompt: Give me an AI-written digest of what the tech community has been focused on since January 1st — I want to know the key themes and discussions happening on Hacker News right now.

## When to prefer this

Use this endpoint when you need a concise, human-readable AI-written summary of what the tech/developer community is currently discussing on Hacker News, rather than raw stories or individual post data. Ideal for briefing users on tech trends without requiring them to parse large volumes of content.

## Known failure modes

- No recent Hacker News data available for the requested window — returns empty or minimal digest
- Invalid date-time format for 'since' parameter — schema validation error
- Upstream LLM generation failure — may fall back to template-based generation
- Payment not completed (x402) — endpoint returns 402 Payment Required

## How this service works

## Output

A short LLM-written prose digest summarizing the most notable topics and discussions from the Hacker News tech community within the requested time window, along with a flag indicating whether it was generated by an LLM or template and the number of source items it was based on.
