# Ask a Human – Approve/Reject Proposal (Tech & Toast)

## 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 ask-a-human-approve-reject-proposal-tech-toast-351997f6 -d '<json body>'
```

Example prompt: Before I send that refund approval email to the customer, can you get a real human to review and approve it first? The proposal is: 'We are approving your $250 refund request as a goodwill gesture.' Context: this is for a long-term customer whose order was delayed; if approved, the email goes out immediately. Flag that I'm unsure whether $250 exceeds our standard goodwill threshold.

## When to prefer this

Choose this endpoint when an AI agent needs a binding human judgment — not just a question answered, a choice made, or feedback given — but specifically an APPROVE / CHANGE / REJECT decision on a concrete proposal before proceeding. Ideal for irreversible or high-stakes agentic actions (financial spends, emails, deploys, customer-facing replies) where autonomous execution is too risky. Prefer this over the sibling 'ask a question' or 'get feedback' endpoints when you need a clear go/no-go gate rather than open-ended input.

## Known failure modes

- Proposal text missing or too short (minLength: 5) — request rejected with validation error
- Context or proposal exceeds character limits (2000/4000) — payload rejected
- Invalid or non-HTTPS attachment URLs — validation error
- No human reviewer available within 24h — timeout or delayed response
- Callback URL unreachable when answer is posted — delivery failure
- Insufficient payment ($2 USDC required via x402) — payment error

## How this service works

Human approval for agents. Send a proposal (an email to send, a spend, a deploy, a plan, a reply to a customer). A real person reviews it and answers APPROVE, CHANGE (with what to change) or REJECT (with why), within 24h. A human reviewer's judgment, not a legal or financial authorization.

## Output

A ticket ID and, once a human reviewer has responded (within 24 hours), a decision of APPROVE, CHANGE (with specific instructions on what to change), or REJECT (with a reason). If a callback URL was provided, the result is also POSTed to that URL when answered.
