## 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-943a6b9f -d '<json body>'
```

Example prompt: What's the current developer sentiment on HackerNews for Svelte — is it trending positively or negatively, and how fast is it moving on the front page?

## When to prefer this

Choose this endpoint when you need real-time, live developer community sentiment specifically from HackerNews discussions rather than social media or general web sentiment. It is ideal for tracking how the tech community reacts to frameworks, AI models, startups, and libraries at the moment of query, especially for developer-focused products where HackerNews is the primary opinion-forming forum.

## Known failure modes

- Empty or whitespace query string returns a validation error
- Very niche or obscure topic keywords may return sparse or no HackerNews data
- Payment failure (HTTP 402) if x402 USDC micropayment is not completed
- Timeout if HackerNews API is slow or rate-limiting at query time
- Generic or overly broad queries may yield low-signal sentiment results
