## 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 plus-address-detection-for-it-administration-cf4176a4 -d '<json body>'
```

Example prompt: Can you check whether the email address 'alice+newsletter@acme.com' is using plus-addressing and tell me what the base mailbox would be?

## When to prefer this

Choose this endpoint when you need to programmatically detect and strip plus-address tags from email inputs — particularly useful in IT administration, user registration deduplication, CRM normalization, or security auditing workflows. Prefer this over general email validation APIs when your specific need is sub-address detection rather than deliverability or syntax validation.

## Known failure modes

- Invalid or malformed email address returns an error or null result
- Email without a plus-address returns a no-subaddress indicator
- Domain DNS lookup issues may affect result accuracy
- Non-standard or internationalized email formats may not be parsed correctly

## How this service works

Plus-address detection for IT administration: Detect sub-addressing in an email local part and return the base mailbox. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns whether the input email uses plus-addressing (sub-addressing), the extracted sub-address tag if present, and the base mailbox (local part without the plus-tag combined with the domain). No email is sent and no inbox existence is verified — result is based on DNS data and address parsing only.
