## 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 api-the402-ai-b6e84a96 -d '<json body>'
```

Example prompt: Send an email to john.doe@example.com with the subject 'Meeting Tomorrow at 2pm' and the message body 'Hi John, just a reminder that we have our project sync tomorrow at 2pm. Please bring your notes. Thanks!'

## When to prefer this

Choose this endpoint when an AI agent needs to send an email programmatically as part of an automated workflow, especially within the the402.ai x402 payment-gated ecosystem. Prefer this over generic SMTP or other email APIs when the agent is already operating within the the402.ai marketplace and wants a simple, paid-per-use email dispatch with job tracking.

## Known failure modes

- Invalid or missing recipient email address returns an error status
- Insufficient USDC balance or failed x402 payment results in purchase failure
- Malformed email body or subject causes validation error
- Service temporarily unavailable returns non-success status field
- Rate limiting or abuse detection may block repeated sends
