## 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-13165612
```

Example prompt: What's the current developer sentiment and HackerNews buzz around Bun.js — is it trending, and are discussions positive or negative?

## 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 ideal for gauging technical community reception of frameworks, AI models, open source libraries, or developer-focused startups, especially when front-page velocity and discussion momentum matter. Prefer this over general sentiment APIs when the target audience is specifically software engineers and technical decision-makers.

## Known failure modes

- Empty or whitespace query returns validation error
- Very niche or obscure topic may return low-confidence sentiment due to sparse HackerNews mentions
- HackerNews API downtime may cause stale or unavailable results
- Overly broad queries (e.g. 'software') may produce noisy or unactionable sentiment aggregates
- Payment failure via x402 returns 402 status before processing
