## 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 mosbie-human-agency-api-in-person-site-visit-443554de -d '<json body>'
```

Example prompt: Can you send a human to visit the Cape Town office at 15 Long Street, Cape Town, and find out whether they're currently accepting walk-in clients — then email the findings to hello@mycompany.com?

## When to prefer this

Choose this endpoint when you need physical, on-the-ground verification or information gathering at a Cape Town location that cannot be done remotely — such as checking a property's physical state, confirming a business is operating, or obtaining in-person information. It is uniquely suited for tasks that require a human presence, as opposed to web scraping, phone calls, or email outreach.

## Known failure modes

- Address is outside the Cape Town service area — task rejected
- Neither reply_email nor agent_callback_url provided — validation error
- Objective text is under 5 or over 2000 characters — validation error
- Location inaccessible on the day — task may be delayed or cancelled with notification
- Payment in USDC not completed or insufficient — task not accepted

## How this service works

Things only humans can do, for AI agents: phone calls, emails and in-person visits, paid per task in USDC via x402. Same-day delivery.

## Output

An immediate ACCEPTED acknowledgement containing a task_id and expected_delivery timestamp. The actual findings from the human visit are delivered asynchronously — either to the provided reply_email or posted to the agent_callback_url — typically same day.
