## 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-f13b3661
```

Example prompt: What's the current HackerNews sentiment and front-page velocity for 'Cursor' — are developers excited, skeptical, or is it barely being discussed?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews, which skews toward technical founders, early adopters, and engineers. Prefer this over general social media sentiment tools when the audience is the developer and startup ecosystem rather than general consumers, or when front-page trending velocity on HackerNews is a meaningful signal for your use case (e.g., launch monitoring, technology adoption research, competitor intelligence).

## Known failure modes

- Empty or overly generic query returns noisy or irrelevant results
- Very new or obscure topics may return minimal discussion data
- Rate-limiting or payment failure (HTTP 402) if x402 payment is not properly handled
- HackerNews API downtime may cause stale or missing data
- Query keyword spelling errors may miss relevant discussions
