## 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 workflows-agentdiet-dev-hackernews-developer-ecosystem-real-time-00903d98
```

Example prompt: What's the current developer sentiment and HackerNews buzz around Bun.js — how fast is it moving on the front page and what are people actually saying about it?

## When to prefer this

Choose this endpoint when you need real-time, developer-specific sentiment from the HackerNews community rather than general social media or Twitter sentiment. It is especially valuable for evaluating developer tools, open-source libraries, AI models, and tech startups where HackerNews is the primary community discussion forum. Prefer this over generic web scraping when you want structured velocity and sentiment signals rather than raw HTML.

## Known failure modes

- Empty or ambiguous query string returns no meaningful results
- Very niche or brand-new topics may have insufficient HackerNews data to produce reliable sentiment
- HackerNews API rate limits or downtime could result in incomplete data
- Topics with extremely common words may return noisy, off-topic discussions
- Payment failure via x402 returns 402 and no data
