## 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 polymarket-odds-agentdiet-dev-hackernews-developer-ecosystem-real-4d10f33a -d '<json body>'
```

Example prompt: What is the current HackerNews sentiment and front-page velocity for 'Llama 3' — are developers excited, skeptical, or indifferent about it?

## When to prefer this

Choose this endpoint when you need real-time, developer-specific sentiment and community discussion velocity from HackerNews — particularly for evaluating how the technical community perceives a framework, startup, or AI model. Prefer this over general social media sentiment APIs when the target audience is specifically developers and engineers, or when front-page HackerNews traction is a key signal. Not suited for broad consumer sentiment (use Twitter/Reddit APIs instead) or historical trend analysis.

## Known failure modes

- Empty or vague query string returns no meaningful results
- HackerNews API rate limiting may delay or truncate live results
- Very niche or newly coined terms may return sparse discussion data
- Network timeout if HackerNews upstream is slow or unavailable
- Payment failure (HTTP 402) if x402 USDC balance is insufficient
