## 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 agentdiet-dev-hackernews-developer-ecosystem-real-time-sentiment-pulse-a2b9310d
```

Example prompt: What's the current developer sentiment and HackerNews discussion velocity around 'Bun' — is it trending positively or negatively among hackers right now?

## When to prefer this

Choose this endpoint when you need real-time developer community opinion and HackerNews-specific discussion velocity for a technology, framework, startup, or AI model. It is particularly valuable for gauging hacker/developer sentiment rather than general social media sentiment, tracking whether a topic is currently trending among technical audiences, or assessing community reception of a new product or library launch.

## Known failure modes

- Empty or very niche query returns no matching HackerNews discussions
- Payment not processed results in HTTP 402 response blocking access
- Query too broad returns noisy or unfocused sentiment data
- HackerNews API rate limits or downtime cause stale or failed results
- Ambiguous keyword (e.g. a common word) may match unrelated discussions
