## 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-structure-check-for-sales-operations-1e72abd6 -d '<json body>'
```

Example prompt: Can you check whether 'john.doe@acmecorp.com' has a valid email syntax and properly formatted domain — just the structure check, no need to actually send anything?

## When to prefer this

Use this endpoint when you need a lightweight, fast check of email address syntax and domain formatting without triggering any email sends or inbox verification. Ideal for pre-screening sales leads, cleaning contact lists, or validating form inputs at low cost ($0.01/call). Prefer this over full email verification services when you only need structural validity and want to avoid deliverability testing overhead.

## Known failure modes

- Malformed input (non-string or missing email field) returns an error
- DNS lookup failures may affect domain validation results
- Does not detect catch-all mail servers or existing mailboxes — may return valid for non-existent addresses
- Disposable or temporary email domains may still pass structural validation

## How this service works

Email structure check for Sales operations: Check syntax and domain formatting only; it does not test whether a mailbox exists. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns a validation result indicating whether the email address passes syntax and domain formatting checks, based on DNS data. Does not confirm whether a real mailbox exists or send any email.
