## 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-email-task-c7b9fce7 -d '<json body>'
```

Example prompt: Have a real human send an email to jane.smith@acmecorp.com asking whether they offer net-30 payment terms for new vendors, and post the result back to https://myapp.com/callback/mosbie when it's done.

## When to prefer this

Choose this endpoint when your agent needs a real human to send an email — particularly when a human sender is more likely to get a response than an automated system, when the email requires nuanced judgment or natural language that should appear authentically human, or when contacting businesses or individuals who filter or ignore automated outreach. Prefer this over automated email APIs when human credibility and same-day delivery matter.

## Known failure modes

- Missing required fields (objective or recipient_email) returns a validation error
- Invalid or malformed recipient_email causes task rejection
- Neither reply_email nor agent_callback_url provided may cause result delivery failure
- Payment failure via x402 prevents task acceptance
- Recipient does not respond, resulting in no outcome reported back
- Invalid agent_callback_url causes callback delivery failure

## 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

Returns a JSON object confirming the task was accepted, including a unique task_id for tracking, a task_status of ACCEPTED, and an expected_delivery timestamp. The actual email outcome is delivered asynchronously to the provided reply_email or agent_callback_url once a human has completed the task.
