Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ryan-sproule-email-api-18856a0a -d '<json body>'
```

Example prompt: Send an email through the ryansproule.com email API to notify john@example.com that their order has shipped.

## When to prefer this

Use this endpoint when you need a simple, pay-per-call email sending capability without setting up a full email service provider account. Suitable for lightweight automation or one-off email notifications that require a minimal integration footprint.

## Known failure modes

- Invalid or missing recipient email address returns an error
- Malformed request body causes a 400 Bad Request
- Authentication or payment failure prevents the email from being sent
- Network timeout or server unavailability results in no delivery confirmation
- Recipient domain rejects the message, possibly returning ok: false
