## 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-check-4b2ff1c1 -d '<json body>'
```

Example prompt: Can you check whether john.doe@example.com is a valid email address — verify the syntax, confirm the domain has real MX records, and flag it if it's from a disposable email provider?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call email validation that covers syntax, DNS MX record existence, and disposability detection without requiring an API key or account setup. Ideal for agents that need to validate individual email addresses on-demand and pay via x402/USDC micro-transactions on Base.

## Known failure modes

- Invalid or malformed input JSON returns an error
- DNS lookup may timeout or fail for obscure TLDs
- Disposability database may not cover all temporary email providers
- Non-existent domains return MX check failure
- Network issues on the AmanChain node may cause timeouts

## 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 validation results indicating whether the email address has correct syntax, whether the domain has valid DNS MX records (meaning it can receive mail), and whether the address belongs to a known disposable/temporary email provider.
