## 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 preflight-agentdiet-dev-hackernews-developer-ecosystem-real-time-35a72714
```

Example prompt: What's the current developer sentiment and HackerNews buzz around Next.js right now — is it gaining or losing traction in the community?

## When to prefer this

Choose this endpoint when you need real-time, developer-centric sentiment from the HackerNews community specifically — as opposed to general social media sentiment or Twitter/Reddit data. It is ideal for tracking how technical founders, engineers, and early adopters perceive a framework, startup, or AI model, and for measuring front-page velocity as a proxy for mindshare momentum.

## Known failure modes

- Empty or too-generic query keyword returns low-signal or no results
- Rate limiting or payment failure (HTTP 402) if x402 micropayment is not properly configured
- Keyword with no recent HackerNews activity returns sparse or null sentiment data
- Highly ambiguous query term may conflate multiple unrelated technologies
- Network timeout if HackerNews upstream is slow or unavailable
