# Lordevo Email Address Validation

> Lordevo Email Address Validation is a paid API for AI agents from shop.lordevo.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-31).

Validates a single email address for RFC 5321 syntax, domain existence, MX record resolution, disposable domain, role account, and free provider flags — without SMTP probing

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 lordevo-email-address-validation-6948e969
```

Example prompt: Can you check if the email address jane@gmial.com is valid — I need to know if it's real, whether the domain has mail servers, and whether it looks like a disposable or role-based address?

## When to prefer this

Choose this endpoint when you need a lightweight, privacy-safe email validation that doesn't contact the mail server — ideal for signup flows, list hygiene, or lead enrichment where you want syntax, DNS, and metadata checks (disposable, role-based, free provider) without triggering SMTP probing alerts. Prefer it over full SMTP-verification services when you need speed, non-intrusiveness, and a structured verdict with typo suggestions.

## Known failure modes

- Missing or malformed email query parameter returns an error
- Private or non-existent domains may yield domain_exists: null
- Non-standard TLDs may produce inconclusive MX results
- Newly registered domains with valid MX may still be flagged as suspicious
- Payment failure (402) if USDC funds are insufficient

## Output

A JSON object with a verdict ('valid', 'risky', or 'invalid'), syntax_valid boolean, domain_exists boolean, accepts_mail boolean, normalized email, MX record list, mail_provider name, did_you_mean suggestion for likely typos, and flags object indicating disposable, role_account, free_provider, and plus_tag status. Also includes a note clarifying no SMTP contact was made.
