## 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 x402-orth-sh-email-verification-code-sender-d8a8a0eb -d '<json body>'
```

Example prompt: Send a 6-digit one-time verification code to jane.doe@example.com to verify her email — use en-US locale and include her IP address 203.0.113.42 and device ID abc-123 for fraud detection.

## When to prefer this

Choose this endpoint when you need to send OTP codes via email with built-in fraud detection signals (IP, device ID, user agent) and Didit's verification infrastructure. It is preferable over generic email APIs when you need a dedicated OTP flow with configurable code sizes and locale support, and when you want to pass anti-fraud context alongside the send request.

## Known failure modes

- Invalid or malformed email address returns a validation error
- Email delivery failure due to SMTP issues or spam filters
- Invalid code_size value outside the 4-8 range returns a parameter error
- Missing required email field returns a 400 bad request
- Fraud signals triggering a block or rate limit on the request
- Network timeout resulting in uncertain delivery status

## How this service works

Send a one-time verification code to an email address.
