## 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-fa97eac7
```

Example prompt: What's the current HackerNews sentiment and front-page velocity around 'Svelte' — are developers excited or skeptical about it right now?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — ideal for tracking how technical audiences perceive a new framework, AI model, startup, or library. Prefer this over general social media sentiment tools when the target audience is developers and engineers, or when front-page velocity on HackerNews is a meaningful signal (e.g. launch monitoring, competitive research, investment due diligence on dev tools).

## Known failure modes

- Empty or whitespace query string returns validation error
- Query returns no results if topic has no recent HackerNews activity
- Rate limiting or payment failure (HTTP 402) if USDC micropayment is not included
- Ambiguous keywords may return mixed results across unrelated topics
- HackerNews API downtime may cause empty or stale results
