## 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-compiler-agentdiet-dev-hackernews-developer-ecosystem-real-time-e731497c -d '<json body>'
```

Example prompt: What's the real-time developer sentiment and HackerNews front-page velocity for 'Deno' right now — are people excited or skeptical about it?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — ideal for tracking launch reactions, framework adoption trends, AI model reception, or startup buzz among technical audiences. Prefer this over general social sentiment APIs when the target audience is developers and the signal source should be HackerNews specifically.

## Known failure modes

- Empty or irrelevant query string returns no meaningful results
- Topic with no recent HackerNews coverage returns low-confidence or empty sentiment data
- Payment failure (HTTP 402) if x402 micropayment is not properly configured
- Rate limiting or network timeout if HackerNews API is slow or unavailable
- Overly broad query (e.g. 'AI') may return noisy or ambiguous sentiment data
