## 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-c8ba88c3
```

Example prompt: What's the current HackerNews sentiment and discussion velocity around Anthropic's Claude right now — are developers excited, skeptical, or mixed?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment from HackerNews rather than broad social media sentiment. It is best for gauging how technical practitioners — engineers, founders, and researchers — are currently reacting to a specific framework, AI model, startup, or library. Prefer it over generic web search sentiment tools when the audience is specifically developers and the source fidelity of HackerNews matters.

## Known failure modes

- Empty or very niche query returns no HackerNews results
- Payment failure via x402 if USDC balance is insufficient
- Rate limiting if excessive queries are made in short succession
- Ambiguous keyword (e.g. 'apple') may return mixed or irrelevant discussions
- Service unavailability returns non-200 response with no sentiment data
