## 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-59d5564b -d '<json body>'
```

Example prompt: What's the real-time developer sentiment and front-page velocity on HackerNews right now for 'Ollama' — are developers excited or skeptical about it?

## When to prefer this

Choose this endpoint when you need live developer community sentiment specifically from HackerNews — ideal for gauging technical reception of new frameworks, AI models, startups, or libraries among software engineers. Prefer it over general web search when the target audience is developers and you want community-driven discussion velocity rather than marketing content.

## Known failure modes

- Empty or ambiguous query returns low-signal or no results
- Topic with very little HackerNews activity may return sparse data
- Rate limiting or payment failure (HTTP 402) if USDC micropayment not processed
- Transient HackerNews Algolia API outage causing partial or no results
- Very broad keywords (e.g. 'AI') may return unfocused, low-utility results
