## 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-closed-choice-multiple-choice-question-1242da32 -d '<json body>'
```

Example prompt: Before I send the apology email to the client, ask a real human which version feels more sincere — give them these two options: 'We sincerely apologize for the delay and are working to fix it immediately.' or 'We're sorry about this — it's on us and we're on it.' They have up to 24 hours to pick one.

## When to prefer this

Use this endpoint when you need a human to choose from a predefined set of options — such as which message tone feels right, which option they'd prefer, or whether to approve an action — and the answer cannot be derived from facts, code, or AI reasoning alone. Prefer this over the open-answer sibling endpoint when the possible responses are bounded and you want a clean, unambiguous selection. Not appropriate for factual lookups, code generation, real-world physical tasks, or any use case requiring a free-text written response.

## Known failure modes

- Human does not respond within 24 hours — request is marked expired and payment refunded
- Human declines the question — request is marked declined and payment refunded
- Question exceeds 50-word limit — request rejected at submission
- Fewer than 2 or more than 6 options provided — schema validation error
- follow_up_of job_id does not match a valid prior job — error returned
- Invalid refund_address format — schema validation error
- Payment of $1 USDC not received — request not created

## How this service works

Ask a real person a multiple-choice question: how a message feels, which option a person would prefer, or whether to go ahead with an action before you take it. Send 'question' and 2-6 'options'; a human picks one within 24 h. Poll the returned status_url. Not for facts or code. Declined or late requests are refunded.

## Output

Returns a status URL to poll for the human's answer. Once the person responds (within 24 hours), the polled status endpoint reveals which option they selected. If the request is declined or times out, the $1 USDC payment is refunded to the paying or specified refund address.
