## 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 whale-momentum-agentdiet-dev-hackernews-developer-ecosystem-real-time-8a754115
```

Example prompt: What's the current HackerNews sentiment around 'Cursor IDE' — are developers excited, skeptical, or indifferent? Pull the live discussion pulse for me.

## When to prefer this

Choose this endpoint when you need real-time, live developer community sentiment specifically from HackerNews — especially for tech startups, programming frameworks, AI models, or YC launches. It is ideal when you need front-page velocity and discussion momentum, not historical data or broad social media sentiment across Twitter or Reddit. Prefer this over generic web scraping when you want structured, pre-analyzed developer opinion rather than raw HTML.

## Known failure modes

- Empty or very niche query with no HackerNews activity returns sparse or empty results
- HackerNews API rate limits or downtime cause upstream fetch failures
- Overly broad single-word queries (e.g. 'AI') may return unfocused or overwhelming sentiment signals
- Payment failure via x402 micropayment protocol returns 402 status before any data is fetched
- Misspelled or non-existent product names return no matching discussions
