## 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 defi-yield-agentdiet-dev-hackernews-developer-ecosystem-real-time-655b5c56
```

Example prompt: What's the current developer sentiment and HackerNews discussion velocity around the Deno runtime — are people excited, skeptical, or is it barely being mentioned?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment rather than general social media sentiment — it is purpose-built for HackerNews discussions and front-page velocity, making it ideal for evaluating how technical practitioners view a framework, startup, or AI model at a specific moment in time.

## Known failure modes

- Missing required 'query' parameter returns a validation error
- Empty or very short query string may return sparse or no results if the topic has no recent HackerNews coverage
- Highly obscure or misspelled technology names may yield zero sentiment data
- Rate limiting or payment failure (HTTP 402) if the x402 micropayment is not correctly handled
- HackerNews upstream latency spikes may cause delayed or timeout responses
