## 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 serp-extract-agentdiet-dev-hackernews-developer-ecosystem-real-time-67c757d5 -d '<json body>'
```

Example prompt: What's the current HackerNews sentiment and front-page buzz around 'Cursor' — are developers excited, skeptical, or mixed on it right now?

## When to prefer this

Choose this endpoint when you need real-time developer community opinion and HackerNews-specific discussion velocity for a technology, startup, or AI model — especially useful for competitive intelligence, launch reception monitoring, or gauging grassroots developer adoption signals rather than general web sentiment.

## Known failure modes

- Empty or whitespace query string returns validation error
- Niche or very new topics may return sparse or no results
- Rate limits or payment failures (HTTP 402) may block execution
- HackerNews API downtime causes upstream data gaps
- Ambiguous keywords may return mixed/irrelevant results
