## 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

Example prompt: What's the live developer sentiment on HackerNews around 'Rust' right now — are people excited, skeptical, or mixed?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment from HackerNews rather than broad social media sentiment. It is best suited for gauging how technical audiences (engineers, founders, researchers) are reacting to a framework, library, AI model, or startup, especially when front-page velocity or trending discussion depth matters.

## Known failure modes

- Empty or too-generic query returns low-signal results
- Topic not discussed on HackerNews returns minimal or no data
- Payment failure (HTTP 402) if x402 USDC payment is not completed
- Rate limiting if too many calls are made in rapid succession
- Ambiguous keyword matches unintended topics on HackerNews
