## 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 alpha-stream-agentdiet-dev-hackernews-developer-ecosystem-real-time-3591bda7
```

Example prompt: What's the live developer sentiment on HackerNews about LangChain right now — is it trending, and are people generally positive or negative about it?

## When to prefer this

Choose this endpoint when you need real-time, live developer community sentiment specifically from HackerNews — particularly for evaluating how a framework, AI model, library, or startup is perceived among technical audiences right now. Prefer this over generic social media sentiment tools when the target audience is specifically developers and the HackerNews community, or when front-page velocity and discussion momentum are relevant signals.

## Known failure modes

- Empty or overly generic query keyword returns sparse or irrelevant results
- Very new or obscure topics with no HackerNews activity may return empty sentiment data
- Rate limiting or payment failure (HTTP 402) if USDC micropayment is not processed
- Ambiguous keyword matching multiple technologies may produce mixed or noisy sentiment
- HackerNews API downtime may cause stale or unavailable data
