## 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-24b83b70 -d '<json body>'
```

Example prompt: What's the current HackerNews sentiment and discussion velocity around the Llama 3 model — are developers excited, skeptical, or mixed?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical signal source for technical opinion leaders and early adopters. Prefer this over general social media sentiment tools when your audience is developers, CTOs, or technical founders, and you need front-page velocity data alongside discussion content rather than raw mention counts.

## Known failure modes

- Empty or too-broad query returns noisy or irrelevant HN threads
- Very niche or obscure topics may return zero results with empty sentiment data
- HackerNews Algolia API downtime causes upstream fetch failure
- Rate limiting or payment failure (HTTP 402) blocks the request
- Misspelled technology names may match unrelated discussions
