## 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 email-address-normalization-for-security-review-ba192e8f -d '<json body>'
```

Example prompt: Can you normalize the email address 'User+Newsletter@Example.COM' and tell me if it has a plus-address tag, using DNS data only without sending any mail?

## When to prefer this

Use this endpoint when you need to canonicalize email addresses and detect plus-address subaddressing for security, fraud detection, or deduplication purposes without triggering any mail delivery or requiring inbox verification. Prefer this over full email verification services when you only need structural normalization and tag extraction with no side effects.

## Known failure modes

- Malformed email address input returns a validation error
- Email domain not resolvable via DNS may limit domain-level normalization
- No plus tag present returns an empty or null tag field
- Non-standard email formats (e.g. quoted local parts) may not parse as expected

## How this service works

Email address normalization for Security review: Normalize case and identify a plus-address tag without sending mail. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns the normalized (case-folded) form of the email address and identifies any plus-address tag present in the local part, based on DNS data only. No email is sent and no inbox existence is verified.
