## 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 mesh-agentdiet-dev-hackernews-developer-ecosystem-real-time-sentiment-25e83b3b
```

Example prompt: What's the current developer sentiment around LangChain on HackerNews — are people excited, critical, or lukewarm about it right now?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical signal source for technical founders, engineers, and early adopters. Prefer this over general social media sentiment tools when your audience is developers or when evaluating technical products, frameworks, or AI models where HackerNews discussion quality and velocity are meaningful signals.

## Known failure modes

- Empty or very niche query returns no matching HackerNews discussions
- Payment not fulfilled via x402 results in 402 Payment Required response
- Query too broad returns noisy or inconclusive sentiment data
- HackerNews Algolia API unavailability causes downstream failure
- Rate limiting if too many queries are issued in rapid succession
