## 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-b637090f -d '<json body>'
```

Example prompt: What's the current developer sentiment and front-page velocity on HackerNews for 'Deno' — are people excited, skeptical, or is it barely getting traction?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment rather than general social media sentiment. It is ideal for understanding how technical audiences on HackerNews perceive a specific framework, startup, or AI model, especially when front-page traction and comment-level developer opinion matter more than Twitter volume or Reddit upvotes.

## Known failure modes

- Empty or overly broad query returns noisy or irrelevant results
- Very niche or obscure topic with no HackerNews activity returns empty or minimal data
- Rate limiting or payment failure (HTTP 402) if USDC balance is insufficient
- Ambiguous topic keyword matches unrelated HackerNews threads
- Intermittent real-time data latency if HackerNews API is slow or rate-throttled
