## 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 agentrxi-email-send-1d51982b
```

Example prompt: Send an email to jane.doe@example.com with the subject 'Your appointment is confirmed' and body 'Hi Jane, your appointment is scheduled for Thursday at 3pm. Please reply if you need to reschedule.' — use the display name 'Acme Scheduling Assistant' and set reply-to as support@acme.com.

## When to prefer this

Choose this endpoint when an AI agent needs to send a single plain-text email to one recipient with transparent AI-sender attribution and built-in compliance (unsubscribe footer, anti-abuse controls). It is ideal for agentic notification workflows, appointment confirmations, order updates, or alerts where regulatory-friendly sending with automatic AI disclosure is required. Prefer it over raw SMTP or bulk email APIs when you want per-send micropayment billing via x402 and don't need HTML formatting or bulk sending.

## Known failure modes

- Rate limit exceeded (20 emails/wallet/day or 5 for new wallets)
- Recipient limit exceeded (max 2 emails per recipient per wallet)
- Wallet blocked due to complaints
- Anti-abuse policy violation (phishing, credential requests, link shorteners, brand impersonation)
- Invalid or malformed recipient email address
- Subject line exceeds 150 characters
- Body exceeds 10,000 characters or contains more than 5 links
- Payment not provided or insufficient (requires $0.009 USDC)

## How this service works

Send one plain-text email to one recipient from agent@mail.agentrxi.com, with your display name and an optional reply-to. Every message carries a footer naming the AI sender with one-click unsubscribe. Anti-abuse: 20 emails per wallet per day (5 for new wallets), 2 per recipient per wallet, no phishing, credential requests, link shorteners or brand names; wallets that draw complaints are blocked. Also callable as GET with the same fields as query parameters.

## Output

Returns a confirmation object indicating whether the email was successfully queued or delivered, including a message ID or status field. On failure, returns an error indicating the reason (e.g., rate limit exceeded, invalid recipient, anti-abuse policy violation).
