## 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-cb8ae95f
```

Example prompt: What's the current HackerNews sentiment and front-page velocity for 'LangChain' — are developers excited, skeptical, or indifferent about it right now?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical signal for how technical builders perceive a technology, startup, or AI model. Prefer this over generic social media sentiment tools when your audience is developers or when HackerNews front-page velocity is a meaningful signal (e.g. assessing tech adoption, competitive positioning, or startup traction within the engineering community).

## Known failure modes

- Empty or very niche query returns no results if the topic hasn't been discussed on HackerNews
- HackerNews Algolia API downtime may cause delayed or failed responses
- Overly broad queries may return noisy, unfocused sentiment data
- Rate limiting or payment failure (HTTP 402) if the $0.01 per-call payment is not settled
- Sentiment may lag for very recent news if HackerNews indexing hasn't caught up
