## 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-96352246 -d '<json body>'
```

Example prompt: What's the current developer sentiment on HackerNews for Next.js — is it trending positively or negatively among engineers right now?

## 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 velocity and engineering community discourse. Prefer it over generic web scraping or Twitter sentiment tools when your target audience is developers, founders, or technical evaluators who frequent HackerNews.

## Known failure modes

- Empty or overly generic query string returns low-confidence or no matching discussions
- Very niche or obscure topics may return minimal HackerNews data
- Payment failure or x402 authorization issues block the request
- Rate limiting if the same query is retried rapidly without an idempotency key
- HackerNews API downtime may cause incomplete or stale results
