## 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 hn-pulse-agentdiet-dev-hackernews-developer-ecosystem-real-time-e29eb86a -d '<json body>'
```

Example prompt: What's the current developer sentiment around Rust on HackerNews — is it trending on the front page and are devs generally positive or negative about it?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment rather than general social media sentiment. It is ideal for evaluating how technical audiences perceive a framework, AI model, or startup, especially when HackerNews is the authoritative signal for developer adoption. Prefer this over general web search when you want community velocity (front-page traction) and qualitative developer opinion specifically from the Hacker News ecosystem.

## Known failure modes

- Empty or too-generic query string returning low-signal results
- Topic too niche to have meaningful HackerNews coverage, resulting in sparse data
- Payment failure via x402 micropayment protocol blocking the request
- Rate limiting or quota exhaustion on upstream HackerNews Algolia API
- Transient network errors reaching the live HackerNews data source
