## 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 real-human-opinions-search-200792c2
```

Example prompt: Search for real human opinions about mechanical keyboards on PTT and Hacker News — I only want genuine user discussions, not AI-generated content, and ideally posts from before ChatGPT launched.

## When to prefer this

Choose this endpoint when you need authentic, verifiable human opinions from community forums (PTT, Hacker News, Stack Exchange, Lemmy) and want to explicitly exclude AI-generated content. Especially valuable when researching topics where AI-written reviews or answers have flooded the web post-2022, or when you need Taiwan-specific community perspectives with human verification. Prefer this over generic web search when the goal is to surface pre-ChatGPT era sentiment or to distinguish AI vs human authorship of forum content.

## Known failure modes

- No results found for obscure or niche query terms
- Query too broad returns irrelevant cross-platform noise
- Pre-ChatGPT filter may exclude relevant recent discussions
- Taiwan-specific human verification may be unavailable for some PTT posts
- Rate limiting or payment failure at $0.05 USDC per call via x402 protocol
