> agentdiet Email Validator is a paid API for AI agents from agentdiet.dev, paid per call via x402 or MPP, $0.005/call, status unknown (last checked 2026-10-20).

Validates email addresses for syntax, disposable/burner status, role account detection, and live DNS MX/SPF/DMARC record checks to assess deliverability.

## 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 agentdiet-email-validator-3c750275
```

Example prompt: Can you check whether john.doe@example.com is a real, deliverable email address — specifically whether it's from a disposable provider, whether it's a role account, and whether the domain has valid MX, SPF, and DMARC records?

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call check covering both static validation (syntax, disposable provider detection, role account flagging) and live DNS verification (MX, SPF, DMARC) in one step. Prefer it over basic regex-only validators when deliverability and email authentication posture matter, such as before sending transactional email, onboarding new users, or qualifying B2B leads.

## Known failure modes

- Invalid or missing email query parameter returns an error
- DNS lookup failures for domains with no MX records
- Timeout on slow or unresponsive DNS servers
- False negatives on newly created disposable providers not yet in the blocklist
- Rate limiting or payment failure resulting in 402 response

## How this service works

Validates email syntax, disposable/burner provider status, role accounts, and live DNS MX/SPF/DMARC records. (Live x402 v2, IETF MPP & MCP endpoint at https://agentdiet.dev/v1/email-validator)

## Output

Returns a structured report indicating whether the email passes syntax checks, whether the provider is a known disposable/burner service, whether the address is a role account (e.g. noreply@, info@), and live DNS lookup results for the domain's MX, SPF, and DMARC records — giving an overall deliverability assessment.
