## 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-email-sales-operations-43912d55 -d '<json body>'
```

Example prompt: Can you check if the email address 'john.doe+promo2024@example.com' is using plus-addressing and tell me what the base mailbox actually is?

## When to prefer this

Use this endpoint when you need lightweight, DNS-only plus-address detection without triggering any email send or inbox verification — ideal for CRM deduplication, sales lead normalization, or fraud/abuse detection at sign-up time. Prefer this over full email verification services when you only need to parse sub-addressing structure cheaply and quickly.

## Known failure modes

- Invalid or malformed email address returns an error or null result
- Email with no plus tag returns a negative detection with the original address as the base
- DNS lookup failures may cause degraded results
- Catch-all or unusual domain configurations not reflected in output since no inbox verification is performed

## How this service works

Plus-address detection for Sales operations: 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 submitted email address contains a plus-address sub-tag in the local part, the extracted base mailbox (the portion before the plus sign), and the tag itself, derived from DNS-level data without sending email or verifying inbox existence.
