## 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 domain-osint-agentdiet-dev-hackernews-developer-ecosystem-real-time-2aefecc3 -d '<json body>'
```

Example prompt: What's the current developer sentiment on HackerNews around Bun — are people excited, skeptical, or somewhere in between? Pull the live discussion pulse for me.

## When to prefer this

Choose this endpoint when you need real-time, community-driven developer sentiment specifically from HackerNews — the highest-signal forum for developer and founder opinion. Prefer this over generic web search sentiment tools when the target audience is developers, engineers, or technical founders, and you care about discussion velocity (trending vs. fading) rather than just raw mention counts.

## Known failure modes

- Empty or too-generic query string returns low-signal or no results
- HackerNews Algolia API downtime may cause degraded or empty responses
- Niche or misspelled technology names may return zero matching discussions
- Rate limiting or payment failure (x402) blocks the request
- Response schema is loosely typed — agent must handle variable output shapes
