## 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 serp-extract-agentdiet-dev-hackernews-developer-ecosystem-real-time-d8da6eab -d '<json body>'
```

Example prompt: What's the current developer sentiment on HackerNews around the Rust programming language — are people excited, skeptical, or talking about it at all right now?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical source for technical founder and developer opinion. Prefer it over general social sentiment APIs when the audience is developers, engineers, or technical decision-makers, and when HackerNews front-page velocity is a meaningful signal for your use case.

## Known failure modes

- Empty or too-generic query returns low-confidence or sparse results
- Topic with no recent HackerNews activity may return minimal sentiment data
- Rate limiting or payment failure (HTTP 402) if USDC balance is insufficient
- Ambiguous keyword matching multiple unrelated topics may dilute sentiment accuracy
