## 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-2a90f655 -d '<json body>'
```

Example prompt: Can you normalize the email address 'User+Newsletter@Gmail.COM' — tell me the canonical lowercase form and extract the plus-address tag if there is one?

## When to prefer this

Choose this endpoint when you need to canonicalize or parse an email address for deduplication, storage normalization, or plus-tag extraction, and you explicitly do NOT need to send an email or verify inbox existence. It is DNS-only and read-only, making it safe, fast, and side-effect free for preprocessing pipelines.

## Known failure modes

- Invalid or malformed email address returns an error
- Non-existent domain may return DNS lookup failure
- No plus tag present results in null/empty tag field
- Network timeout on DNS resolution for obscure domains

## How this service works

Email address normalization for Email operations: 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 (lowercased) form of the email address, the extracted plus-address alias tag if present, and basic DNS-derived information about the domain — without sending any email or checking whether the inbox actually exists.
