## 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 request-a-human-open-ended-written-answer-23520970 -d '<json body>'
```

Example prompt: Ask a real human whether this apology email I drafted sounds genuine and not defensive — here's the email: 'I'm sorry if you felt hurt by what I said. I didn't mean it that way.' Give them that context and ask if it comes across as sincere or as deflecting blame.

## When to prefer this

Choose this endpoint when you need a subjective, judgment-based, or socially nuanced answer that only a real human can provide — such as opinions, ethical calls, taste assessments, tone checks, or native-speaker intuitions. Do not use it for factual lookups, code generation, or data processing. Prefer this over LLM-based opinion generation when genuine human perspective and lived experience are required for credibility or authenticity. Use the follow_up_of field when you need continuity with the same respondent across a multi-turn conversation.

## Known failure modes

- Human declines the request — refund issued automatically
- No response within 24 hours — refund issued automatically
- Question exceeds 50-word limit — request may be rejected
- Context exceeds 200-word limit — request may be rejected
- Invalid follow_up_of job_id format — request fails validation
- Invalid refund_address format — request fails validation
- Question is factual or code-related — may be declined as out of scope

## How this service works

Ask a real person for a short written answer where human judgment matters: an opinion, a moral or social call, taste, or native-speaker intuition. Send 'question' (and optional 'context'); a human answers within 24 h. Add follow_up_of to continue a conversation with the same person. Not for facts or code. Declined or late requests are refunded.

## Output

A short written response from a real human, typically a paragraph or a few sentences, reflecting their personal judgment, intuition, or social reasoning on the question posed. The response is delivered asynchronously within 24 hours. If the request is declined or the human doesn't respond in time, a refund in USDC is issued to the specified or paying address.
