## 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 hn-pulse-agentdiet-dev-hackernews-developer-ecosystem-real-time-9cb2249b
```

Example prompt: What's the current HackerNews sentiment and front-page velocity around 'Rust' — are developers excited or skeptical about it 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 or Twitter sentiment. It is ideal for gauging how technical audiences perceive a technology, framework, startup, or AI model — especially useful for competitive intelligence, investment research, developer relations, or product launch monitoring where HackerNews opinion is a leading indicator of developer adoption.

## Known failure modes

- Empty or very niche query terms may return sparse results if the topic has minimal HackerNews coverage
- Rate limiting or payment failure (HTTP 402) if x402 micropayment is not properly configured
- Query too broad (e.g. 'AI') may return noisy or unfocused sentiment aggregates
- Temporary HackerNews API unavailability may cause degraded or stale results
- Misspelled technology names may return no matching discussions
