## 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-8370cfad -d '<json body>'
```

Example prompt: What's the current developer sentiment on HackerNews for LangChain — is there positive buzz, criticism, or is it mostly ignored right now?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment and trend velocity from HackerNews rather than broad social media or general web sentiment. It is ideal for tracking how the technical/developer audience specifically perceives a framework, startup, or AI model, as opposed to mainstream public opinion. Prefer it over generic web search sentiment tools when the HackerNews developer ecosystem opinion is the signal that matters.

## Known failure modes

- Empty or too-generic query returns low-signal or no matching results
- HackerNews Algolia upstream outage causes degraded or empty response
- Highly niche or misspelled query keyword yields zero matching discussions
- Rate limiting or payment failure returns HTTP 402 with payment required details
- Very new topics with no HackerNews history return empty sentiment data
