## 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 hn-pulse-agentdiet-dev-hackernews-developer-ecosystem-real-time-33793c9f
```

Example prompt: What's the current developer sentiment and HackerNews buzz around Rust — are there active front-page discussions and is momentum growing or cooling off?

## When to prefer this

Use this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical forum for technical founders, engineers, and early adopters. Prefer this over general web search when you want structured sentiment velocity (front-page trending) rather than raw search results, and when the audience is specifically the developer/hacker ecosystem rather than general public opinion.

## Known failure modes

- Empty or too-generic query returns low-signal or no results
- Very niche or obscure keyword with no HackerNews coverage returns sparse data
- Payment failure via x402 blocks the request
- Rate limiting if called too frequently
- Response schema is loosely typed (generic object), so output structure may vary
