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.
Example use cases
Agent spend approval before payment
“Before you execute that $1,800 AWS infrastructure spend, get a real human to approve it first. The proposal is: 'Provision 3 additional r6g.xlarge reserved instances for the staging environment.' Context: we're scaling up for Q4 load testing and budget owner is the engineering lead. Flag that this exceeds the $500 auto-approve threshold.”
Customer reply sign-off
“Don't send that reply to the angry customer yet — route it to a human reviewer for approval first. The proposal is: 'We sincerely apologize for the shipping delay and are issuing a full refund plus a 20% discount on your next order.' Context: the customer threatened a chargeback; if approved this goes out immediately via our support email.”
Production deploy gate
“Before the deploy pipeline continues, pause and get a real human to approve this release. The proposal is: 'Deploy v2.4.1 to production, which includes the new payment flow rewrite.' Context: this is a high-risk change to the checkout path during peak sales season. I'm unsure about the rollback time if something goes wrong — flag that as a risk.”
Technical details
Endpoint
POSThttps://ai-to-human.techandtoast.io/api/x402/approve?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
