# MoneyTools Email Validation API

> MoneyTools Email Validation API is a paid API for AI agents from api.moneytools.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-11-05).

Validates an email address for syntax, domain health, MX records, SPF, DMARC, disposable domain, role account status, and typo suggestions — returning a valid/risky/invalid verdict without sending any mail.

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 moneytools-email-validation-api-19577bc9
```

Example prompt: Can you check whether john.doe@gamil.com is a real, deliverable email address — look at the MX records, whether the domain is disposable, and give me a verdict on whether it's valid or risky?

## When to prefer this

Choose this endpoint when you need a comprehensive, non-intrusive email validation that goes beyond simple syntax checking — covering domain health (MX, SPF, DMARC), disposable email detection from a 10k+ domain list, role account flagging, and typo suggestions, all without sending a probe email. Ideal for pre-submission validation in signup flows, CRM enrichment, or lead list hygiene where SMTP probing is undesirable or blocked.

## Known failure modes

- Missing or malformed email query parameter returns an error
- Domains with no MX record may return 'invalid' even if syntax is correct
- Temporary DNS lookup failures may affect MX/SPF/DMARC checks
- Payment not provided or invalid x402 payment header results in 402 response
- Newly registered domains may not yet appear in disposable domain list
