## 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 x402-audit-agentdiet-dev-hackernews-developer-ecosystem-real-time-56d70e32
```

Example prompt: What's the current developer sentiment and front-page velocity on HackerNews for 'Llama 3'? I want to know if the HN community is excited, skeptical, or indifferent right now.

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment from HackerNews rather than general social media sentiment. Ideal for gauging how technical audiences (engineers, founders, early adopters) are reacting to a framework, startup, or AI model — especially for fast-moving topics where HN front-page velocity is a leading indicator of developer mindshare.

## Known failure modes

- Empty or too-broad query returns noisy or irrelevant results
- Niche or very new topic may return sparse data if HN coverage is low
- Payment failure (HTTP 402) if x402 USDC micropayment is not properly handled
- Rate limiting or timeout if HN API is temporarily slow
- Query keyword typos return no relevant threads
