## 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 amanchain-email-validation-mx-962b4d96 -d '<json body>'
```

Example prompt: Can you check if john.doe@example.com is a valid email address — make sure the syntax is correct, the domain has MX records, and it's not a disposable address?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call email validation with no account setup, combining syntax checking, real-time DNS MX verification, and disposable email detection in a single call. Prefer it for agent pipelines where USDC micropayments via x402 are already integrated and you need validation without subscribing to a heavyweight email verification SaaS.

## Known failure modes

- Invalid JSON body or missing required fields returns an error
- DNS lookup timeouts may affect MX record check accuracy
- Unknown or very new domains may not resolve correctly
- Payment failure via x402 prevents the call from being processed
- Disposability list may not cover all throwaway email providers

## How this service works

Email Validation + MX: email validation: syntax, DNS MX records, disposability Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-email-validate","request":"<input>"}. No account, no API key.

## Output

Returns a validation result indicating whether the email address has valid syntax, whether the domain has live DNS MX records (meaning it can receive email), and whether the address belongs to a known disposable or temporary email provider.
