## 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 cve-intel-agentdiet-dev-hackernews-developer-ecosystem-real-time-9f982a35 -d '<json body>'
```

Example prompt: What's the live HackerNews sentiment and front-page buzz around 'Bun' right now — are developers excited, skeptical, or mixed?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment from HackerNews rather than broad social media sentiment. Ideal for evaluating technology adoption, startup reputation among engineers, framework controversy, or AI model reception in the technical community. Prefer over general web search when the target audience is specifically developers or technical founders.

## Known failure modes

- Empty or overly generic query returns low-signal results
- HackerNews API rate limiting may delay or degrade live results
- Very niche or obscure topics with no HN activity return minimal data
- Payment failure via x402 returns 402 with payment instructions
- Ambiguous keyword (e.g. 'apple') may conflate unrelated topics
