## 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 didit-api-didit-email-otp-send-c9670ac6 -d '<json body>'
```

Example prompt: Send a one-time verification code to user@example.com so they can verify their email as part of the Didit identity check.

## When to prefer this

Use this endpoint when you need to verify a user's email address as part of an identity verification or KYC workflow, and you want to deliver a one-time code via email rather than SMS. Prefer this over SMS OTP when the user has provided an email but not a phone number, or when email is the required channel for compliance.

## Known failure modes

- Invalid or malformed email address returns 400 Bad Request
- Email delivery failure due to domain or SMTP issues
- Rate limiting if too many OTPs are sent to the same address in a short window
- Authentication or API key error returns 401 Unauthorized
- Network timeout if the mail delivery service is unavailable

## How this service works

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

## Output

A confirmation that the OTP email was successfully dispatched to the provided email address, including delivery status or a reference ID for the verification session.

## Example request
