## 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 github-audit-agentdiet-dev-hackernews-developer-ecosystem-real-time-6520d1ab
```

Example prompt: What's the current HackerNews sentiment and front-page buzz around 'Cursor IDE' — any trending discussions or developer reactions I should know about?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical signal for technical founders, open-source maintainers, and AI researchers. Prefer this over general social sentiment tools (Twitter/Reddit APIs) when your audience is developers, YC founders, or the technical startup ecosystem, and you need front-page velocity as a proxy for breakout traction.

## Known failure modes

- Empty or very niche query returns no HackerNews matches — low or zero sentiment signal
- Rate limiting or payment failure returns HTTP 402 requiring USDC micropayment
- Query too broad (e.g. 'software') may return noisy, low-signal results
- HackerNews data latency spikes may result in stale or incomplete sentiment snapshots
- Invalid or missing query parameter returns a 400 validation error
