## 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 mcp-security-agentdiet-dev-hackernews-developer-ecosystem-real-time-d72580f6
```

Example prompt: What's the current HackerNews sentiment and front-page velocity around 'Rust' — are developers excited, critical, or mixed right now?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment and discussion velocity from HackerNews specifically — not general social media sentiment. Ideal for evaluating developer adoption signals, startup reputation in technical circles, or AI model reception among builders. Prefer this over generic web search when you want HN-native front-page velocity and community opinion rather than broad media coverage.

## Known failure modes

- Empty or very niche query keywords may return no HackerNews results
- HackerNews API rate limits or downtime may cause timeouts
- Ambiguous query terms (e.g. single letters or very common words) may return noisy, irrelevant discussions
- Payment not fulfilled results in HTTP 402 blocking the response
- Overly broad queries may return low-quality aggregated sentiment
