# Email Validation with Format, Disposable-Domain & Live MX Check

> Email Validation with Format, Disposable-Domain & Live MX Check is a paid API for AI agents from vending-machine-seven.vercel.app, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).

Validates an email address for format correctness, disposable-domain heuristics, and live DNS MX record presence via DNS-over-HTTPS

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 email-validation-with-format-disposable-domain-live-mx-check-8ef28c0f
```

Example prompt: Can you validate whether john.doe@example.com is a real, deliverable email — check the format, whether it's a throwaway domain, and whether the domain actually has MX records set up?

## When to prefer this

Use this endpoint when you need a three-layer email check (syntax + disposable-domain heuristics + live DNS MX verification) in a single call, especially for outreach pipelines, lead-gen agents, or CRM ingestion flows where deliverability and hygiene matter. Prefer over pure format-only validators when you need live DNS confirmation that the domain can actually receive mail.

## Known failure modes

- Missing email query param — returns 400 or validation error
- Invalid or unparseable email format — ok: false, valid_format: false
- Domain has no MX records — has_mx: false, mx: []
- DoH lookup timeout or DNS resolution failure — may return partial result or error
- Disposable domain detected — reflected in service field and ok flag

## How this service works

Validate email format, disposable-domain heuristics, and live DNS MX records via DoH for outreach and lead-gen agents

## Output

Returns a JSON object with: ok (overall validity boolean), valid_format (format check boolean), has_mx (whether MX records exist), mx (array of MX records from DoH lookup), email (normalized input), and service (domain label or disposable-service name if detected).
