## 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 onchain-risk-agentdiet-dev-hackernews-developer-ecosystem-real-time-2bbcb33c
```

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

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical technical community forum — rather than general social media sentiment. Ideal for tracking how developers react to framework releases, startup launches, or AI model announcements, and for measuring front-page velocity as a proxy for trending interest in the developer ecosystem.

## Known failure modes

- Empty or whitespace query returns validation error
- Very niche or obscure topic with no HackerNews mentions returns empty results
- HackerNews API rate limits or downtime may cause upstream failures
- Misspelled technology names may return low or no signal
- Query too broad (e.g. 'software') may return noisy or unfocused results
