## 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 x402-audit-agentdiet-dev-hackernews-developer-ecosystem-real-time-5f81e38a
```

Example prompt: What's the current developer sentiment on HackerNews around Next.js — any trending discussions or front-page momentum I should know about?

## When to prefer this

Choose this endpoint when you need real-time, live developer community sentiment specifically from HackerNews discussions — ideal for tracking developer opinion on emerging frameworks, AI models, startups, or open-source libraries as it happens. Prefer it over generic social sentiment APIs when the target audience is technical developers and HackerNews is the primary signal source.

## Known failure modes

- Empty or vague query returns no results or irrelevant threads
- Very niche or misspelled topic names may yield zero HackerNews matches
- Payment failure ($0.01 USDC via x402) returns HTTP 402 before data is served
- Rate limiting or upstream HackerNews API unavailability may return 503
