Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 codepulse-api-send-email-notification-84f860a1 -d '<json body>'
```

Example prompt: Send an email to alice@example.com with the subject 'Your order has shipped' and the body 'Hi Alice, your package is on its way and will arrive by Friday. Thanks for your order!'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call email delivery capability with no subscription or API key management — ideal for AI agents that need to send transactional or notification emails on demand, billed per use in USDC via the x402 protocol on Base. Prefer over full email platforms when sending low-volume, event-driven emails without infrastructure overhead.

## Known failure modes

- Invalid recipient email address format causes failure
- Missing required fields (to, subject, body) returns a validation error
- Invalid or missing Resend API key if worker config is not set up
- Network or Resend service outage causes delivery failure
- Insufficient USDC balance to cover the $0.02 per-call fee

## How this service works

Sends automated email notifications using the Resend API.

## Output

A JSON object containing a success boolean, a unique emailId string confirming delivery was queued, a confidence rating, an optional warnings array, and a disclaimer note. Returns supported:true when the operation was handled correctly.
