## 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 shopify-spy-agentdiet-dev-hackernews-developer-ecosystem-real-time-8adc4736
```

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

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment and discussion velocity from HackerNews — as opposed to broad social media sentiment (Twitter/Reddit) or generic web mentions. Ideal for evaluating developer mindshare around OSS libraries, AI models, or tech startups before adoption decisions, launch timing, or competitive analysis.

## Known failure modes

- Empty or too-generic query returns noisy or irrelevant results
- HackerNews upstream API rate limiting causes delayed or partial results
- Niche or very new topics may return zero discussion threads
- Ambiguous keywords (e.g. 'Apple') may conflate unrelated topics
- Payment failure via x402 returns HTTP 402 and no data
