## 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 preflight-agentdiet-dev-hackernews-developer-ecosystem-real-time-6d0cf1da
```

Example prompt: What's the current HackerNews sentiment and discussion velocity around 'Anthropic Claude'? I want to know how the developer community is reacting to it right now.

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical forum for startup, framework, and AI model discourse among technical audiences. Prefer this over general social media sentiment tools when your audience is developers, engineers, or founders, and when you care about front-page velocity and discussion depth rather than volume-based metrics from Twitter or Reddit.

## Known failure modes

- Empty or very niche query returns no HackerNews results
- HackerNews API rate limiting or downtime causes fetch failure
- Ambiguous keyword (e.g. 'apple') may return mixed or irrelevant results
- Payment failure via x402 returns 402 error before query is processed
- Overly broad query returns unfocused or low-signal sentiment data
