## 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 palmyr-email-send-788503a3 -d '<json body>'
```

Example prompt: Send an email from my Palmyr inbox to alice@example.com with the subject 'Your order has shipped' and body 'Hi Alice, your order #1234 is on its way and should arrive by Friday. Thanks for shopping with us!'

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically send outbound emails from an inbox it owns via Palmyr's agent infrastructure, particularly when paying per-call with USDC via x402 is acceptable. Ideal for transactional notifications, autonomous agent communications, and workflows where a dedicated agent-owned inbox is required rather than a shared or third-party SMTP service.

## Known failure modes

- Invalid or non-owned inbox identifier returns an authorization error
- Malformed recipient email address causes a validation failure
- Missing required fields (to, subject, body) returns a 400 bad request
- Payment not attached or insufficient USDC balance causes a 402 payment required error
- Recipient mail server rejection may result in a delivery failure or bounce notification

## How this service works

Send an email from an inbox you own. Body: { to, subject, body, html? }
