## 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 oneshotagent-email-send-cfca28f5 -d '<json body>'
```

Example prompt: Send an email to jane.doe@example.com with the subject 'Your Order Confirmation' and body 'Hi Jane, your order #1234 has been confirmed and will ship within 2 business days. Thank you!'

## When to prefer this

Choose this endpoint when an AI agent needs to send a single outbound email without managing its own SMTP infrastructure or domain — especially useful in agentic workflows where the agent must notify a person, confirm an action, or deliver information via email on behalf of a user, billed per-send at $0.001 USDC.

## Known failure modes

- Invalid or malformed recipient email address returns a validation error
- Missing required fields (to, subject, body) result in a 400 bad request
- Payment failure or insufficient USDC balance prevents the call from completing
- Recipient mail server rejects the message due to spam filters or domain reputation
- Rate limiting if too many emails are sent in a short period
