## 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-5de03d8a -d '<json body>'
```

Example prompt: What's the current HackerNews sentiment and discussion velocity around Bun.js — are developers excited about it, skeptical, or mostly ignoring it?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment from HackerNews rather than general social media sentiment. It is purpose-built for technology, startup, framework, and AI model reception analysis within the developer ecosystem, and is especially valuable for tracking YC launch traction, framework adoption momentum, or gauging how technical communities are responding to a new product or announcement.

## Known failure modes

- Empty or very niche query keyword returns no HackerNews discussions
- Payment failure via x402 protocol results in 402 response before data is returned
- HackerNews Algolia API rate limiting causes timeout or partial results
- Ambiguous keyword matches unrelated topics and returns irrelevant sentiment
- Network latency from live data fetch may cause occasional slow responses
