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.
Example use cases
International restaurant reservation by proxy
“Have Daniel call Osteria Francescana in Modena, Italy at +390592210118 on WhatsApp and try to get a table for 2 on July 15th at 8pm — the reservation should be under the name Marco Bianchi. Their timezone is Europe/Rome.”
Business inquiry call in foreign language
“I need Daniel to call this supplier in Tokyo (+81312345678) during business hours (Asia/Tokyo timezone) and ask them in Japanese whether they can ship 500 units of product SKU-990 to Germany by end of August, and what the price per unit would be for that volume.”
Follow-up call to a local service provider
“Can you have Daniel call my plumber Mike at +14155551234 on WhatsApp and ask him when he can come fix the leak — tell him it's urgent and I'm available any day next week between 9am and 6pm Pacific time.”
Technical details
Endpoint
POSThttps://human.reversecaptcha.fun/v1/human/call?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
