## 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`):

Example prompt: What's the current developer sentiment and HackerNews discussion velocity for Llama 3 right now — are developers excited, skeptical, or is it barely being talked about?

## When to prefer this

Choose this endpoint when you need real-time developer community opinion or discussion momentum specifically from HackerNews — ideal for tech due diligence, framework evaluation, AI model reception tracking, or startup sentiment analysis among a technical audience. Prefer this over general social media sentiment tools when the target audience is specifically developers and engineers.

## Known failure modes

- Empty or missing query string returns a validation error
- Very niche or obscure topic may return sparse or no HackerNews results
- Payment failure via x402 results in 402 response before data is returned
- HackerNews API unavailability may cause upstream timeout or empty results
- Rate limiting may occur under heavy usage
