## 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 prompt-guard-agentdiet-dev-hackernews-developer-ecosystem-real-time-bc43774f -d '<json body>'
```

Example prompt: What's the current HackerNews sentiment and front-page velocity for 'Anthropic Claude'? I want to know what developers are saying right now.

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment from HackerNews specifically — especially for tech-savvy audiences evaluating frameworks, AI models, startups, or open-source libraries. It is ideal over generic web sentiment tools when the target audience is developers and HackerNews signal quality matters more than broad social media coverage.

## Known failure modes

- Empty or very niche query returns no relevant HackerNews results
- Rate limiting or payment failure (HTTP 402 without valid x402 USDC payment)
- Topic too broad returns noisy or unrelated threads
- HackerNews API upstream unavailability causes timeout or partial data
- Malformed query (empty string) rejected by schema validation
