## 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-6aab21cf -d '<json body>'
```

Example prompt: What's the current HackerNews sentiment and discussion velocity around LangChain right now — are developers excited, skeptical, or is it barely being mentioned?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment and HackerNews-specific discussion signals rather than general social media or Twitter sentiment. Best used for tracking how technical audiences (developers, engineers, founders) are reacting to frameworks, AI models, libraries, or startups, especially when front-page velocity and YC/HN community buzz are relevant signals.

## Known failure modes

- Query keyword too broad or ambiguous — results may reflect unrelated topics sharing the same term
- No active HackerNews discussions for the given topic — may return empty or minimal results
- Rate limiting or upstream HackerNews API unavailability — service may return errors or stale data
- Payment failure via x402 — request blocked if USDC micropayment is not processed
