## 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 workflows-agentdiet-dev-hackernews-developer-ecosystem-real-time-3490d0e2
```

Example prompt: What's the current HackerNews sentiment and front-page velocity for 'Bun' — are developers excited or critical about it right now?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment and momentum data from HackerNews rather than general social media sentiment. It is ideal for tracking how technical audiences — engineers, founders, and open-source contributors — are reacting to a specific technology, startup, or AI model at this moment, rather than relying on lagging indicators like review sites or broad social platforms.

## Known failure modes

- Empty or too-broad query keyword returns low-signal or irrelevant results
- Very niche or newly coined terms may return no HackerNews matches
- Payment failure (HTTP 402) if x402 micropayment is not handled by the client
- Rate limiting if the same query is polled too frequently
- Transient upstream HackerNews API unavailability causing delayed or empty responses
