## 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 mcp-security-agentdiet-dev-hackernews-developer-ecosystem-real-time-76dff13a
```

Example prompt: What's the current developer sentiment around LangChain on HackerNews — is it trending positively or negatively, and how active are the discussions?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment from HackerNews rather than broad social media sentiment. Ideal for gauging how the technical community reacts to frameworks, AI models, startups, or libraries, especially when front-page velocity and HN discussion quality matter more than Twitter/Reddit volume.

## Known failure modes

- Empty or very niche query returns no HackerNews results
- HackerNews Algolia API downtime causes failed fetch
- Ambiguous keyword matches unrelated topics, skewing sentiment
- Payment not authorized results in HTTP 402 response
- Rate limiting if called too frequently
