## 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 serp-extract-agentdiet-dev-hackernews-developer-ecosystem-real-time-1c8272f1 -d '<json body>'
```

Example prompt: What's the current developer sentiment on HackerNews about Bun — is it gaining momentum or losing steam, and how fast is it showing up on the front page?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment rather than general social media or news sentiment. It is ideal for gauging how the technical community on HackerNews specifically perceives a framework, startup, AI model, or library, and for tracking front-page velocity as a proxy for buzz. Prefer this over generic web search sentiment when your target audience is developers and the HackerNews community specifically.

## Known failure modes

- Empty or too-generic query returns no meaningful discussions
- HackerNews Algolia upstream outage causes no results
- Query term is misspelled or uses an uncommon alias, returning low-relevance threads
- Payment failure (402) if x402 USDC balance is insufficient
- Rate limiting if too many calls are made in a short window
