## 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 polymarket-odds-agentdiet-dev-hackernews-developer-ecosystem-real-c7448ba6
```

Example prompt: What's the current HackerNews sentiment and front-page velocity for 'Llama 3' — are developers excited, skeptical, or ignoring it?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the primary forum for startup launches, open-source library discussions, and technical community reactions. Prefer it over general social media sentiment tools when your audience is developers, engineers, or the YC/startup ecosystem, and you want front-page velocity as a signal of organic traction.

## Known failure modes

- Missing or empty query parameter returns validation error
- Query returns no results if topic has no recent HackerNews activity
- Ambiguous short queries may return noisy or unrelated discussions
- Rate limiting or payment failure (HTTP 402) if x402 micropayment not processed
- Stale or cached results if HackerNews API upstream is slow
