# Foundry Email Validator

> Foundry Email Validator is a paid API for AI agents from minty-sprout.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-03).

Validates an email address by checking syntax, MX records, disposable domain status, and role account flags to estimate 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 foundry-email-validator-bef9a86e -d '<json body>'
```

Example prompt: Can you validate the email address someone@gmail.com and tell me if it has valid syntax, working MX records, and whether it's a disposable or role account?

## When to prefer this

Choose this endpoint when you need a quick, inexpensive multi-factor email check — syntax plus DNS MX lookup plus disposable and role-account detection — in a single call, especially during user onboarding, lead list cleaning, or fraud prevention flows where you need more than just regex validation but don't need full SMTP handshake verification.

## Known failure modes

- Missing or empty input email returns a validation error
- Malformed JSON body returns a 400 error
- Network timeout reaching MX DNS servers may produce incomplete results
- Very new domains may have MX records not yet propagated, causing false negatives on has_mx
- Service may be temporarily unavailable on the Render free tier with cold start delays

## How this service works

Email validation: syntax, MX records, disposable domain and role account checks. Input: an email address.

## Output

Returns a JSON object containing the parsed domain, a list of MX records, boolean flags for has_mx, valid_syntax, disposable, and role_account, plus a deliverable_guess boolean summarizing overall deliverability likelihood.
