## 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 human-desk-daniel-makes-a-phone-call-on-your-behalf-9731a4e9 -d '<json body>'
```

Example prompt: Can you have Daniel call the front desk at Hotel Bosphorus in Istanbul (+902123456789) on WhatsApp and confirm that my reservation for two nights starting June 10 is still booked under the name Sarah Chen? Ask them to send a confirmation email to sarah@example.com.

## When to prefer this

Use this endpoint when you need a real human to make a live phone or WhatsApp call to a specific number — especially across international borders, in a foreign language, or to accomplish something that requires real-time negotiation, confirmation, or persuasion. It is preferable over automated calling services when the call requires human judgment, natural conversation, or cannot be handled by a bot. Choose this over Daniel's cheaper /ask or /task endpoints specifically when a live voice or WhatsApp call is required.

## Known failure modes

- Daniel declines the request — ticket expires without charge
- Phone number unreachable or not on WhatsApp — Daniel reports back failure
- Call placed outside reasonable timezone window — delay or non-response
- Goal ambiguous or context insufficient — Daniel may ask clarifying questions before calling
- Callback URL not reachable — result only available via polling
- Request expires before Daniel accepts — no charge, but task not completed

## How this service works

You are connecting directly to one real human named Daniel (not an AI, not a crowd). Use it when you need human judgment, a real-world action, or a person to talk to. POST /v1/human/ask ($3): any question, honest opinion, sanity check, or a caring human reply. POST /v1/human/review ($10): website audit, app test, social media audit, video review. POST /v1/human/task ($20): hands-on help such as travel planning and online tasks. POST /v1/human/call ($30): Daniel calls a person or business on WhatsApp in any country on your behalf and reports back. Your payment is verified immediately but only charged when Daniel accepts; declined or expired requests are never charged. Poll GET /v1/human/tickets/{id}?token= (free) or pass callback_url. Answers are Ed25519-signed.

## Output

Returns immediately with a ticket ID, a polling URL, and a token. The actual call outcome — what was said, what was achieved, and any relevant details Daniel obtained — is delivered asynchronously once Daniel completes the call. The response is Ed25519-signed for authenticity. If Daniel declines or the request expires, no charge is made.
