## 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 citiview-email-verification-2ca86055
```

Example prompt: Can you verify whether john.doe@tempmail.com is a real, deliverable email address — check if it passes syntax, has valid MX records, and flag it if it's a disposable or role-based address?

## When to prefer this

Use this endpoint when you need a fast, lightweight email quality check before storing or sending to an address — especially when you want to catch disposable or role-based addresses in addition to basic syntax validation. Prefer this over full send-based verification (which sends an actual email) when you want a non-intrusive, read-only check at signup or data-import time.

## Known failure modes

- Missing or malformed email parameter returns an error
- Non-existent domain with no DNS record may cause MX lookup timeout
- Some newer disposable domains may not yet be flagged in the blocklist
- Network errors during MX lookup may result in inconclusive domain status

## How this service works

Verify an email address: syntax check, domain MX lookup, disposable-domain and role-account flags. Use before sending or storing an address.

## Output

Returns validation results for the submitted email address including: syntax check pass/fail, whether the domain has valid MX records, a disposable-domain flag indicating temporary or throwaway email services, and a role-account flag for addresses like admin@, noreply@, or support@.
