## 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-8b90ac45
```

Example prompt: What's the current developer sentiment on HackerNews around Bun.js — are there active discussions, and is it gaining front-page traction?

## When to prefer this

Use this endpoint when you need real-time developer community sentiment specifically from HackerNews — ideal for gauging technical reception of frameworks, libraries, AI models, or startups among software engineers and builders. Prefer this over general social media sentiment tools when the target audience is developers and the signal source is HackerNews rather than Twitter, Reddit, or mainstream media.

## Known failure modes

- Empty or ambiguous query returns no meaningful results
- Very niche or obscure topics with little HackerNews coverage return sparse data
- Rate limiting or payment failure (HTTP 402) if USDC micropayment is not attached
- HackerNews API or scraping backend temporarily unavailable returns error
- Query too broad (e.g. 'AI') may return overwhelming or unfocused results
