### `validate_email`

- The name "validate_email" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Check an email address: syntax, MX/A records via DNS-over-HTTPS, disposable domain, role address, free provider, typo suggestion for major providers. No SMTP probing. Uses 1 check.
```

### `validate_emails`

- The name "validate_emails" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Check a list of up to 50 email addresses in one call, with the same checks as validate_email. Returns one result per address in the same order plus a summary of verdicts. Uses 1 check per address; addresses whose DNS lookup fails come back with reason dns_error and are not billed. If the key lacks checks for the whole list, nothing is checked or billed.
```

### `validate_phone`

- The name "validate_phone" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text

```
