## 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-4a232d2d
```

Example prompt: What's the current developer sentiment on HackerNews around the Llama 4 model — are people excited, skeptical, or mixed, and how fast is it trending on the front page?

## When to prefer this

Choose this endpoint when you need real-time, live developer community sentiment specifically from HackerNews — the authoritative pulse of the technical and startup ecosystem. Prefer it over general web search when you want structured sentiment signals, front-page trending velocity, and YC/startup-community-specific reactions rather than broad social media opinion. It is especially valuable for evaluating new AI models, open-source frameworks, and startup launches from the perspective of technical founders and developers.

## Known failure modes

- Empty or very short query string returns a 400 validation error
- Topic with no recent HackerNews activity may return sparse or empty results
- Payment failure (HTTP 402) if USDC micropayment via x402 is not properly configured
- Rate limiting or upstream HackerNews Algolia API downtime may cause delayed or failed responses
- Overly broad queries (e.g. 'AI') may return noisy or low-signal results
