How this service works
Email validation API — syntax check, DNS MX record verification and disposable or temporary email detection. Deterministic on-chain execution by the AmanChain node — live consensus state, real blocks, pools and balances. Pay per call via x402 (USDC on Base), no account, no API key. POST JSON {"serviceId":"aman-email-validate","request":"<input>"}.
Output
Returns a structured validation result indicating whether the email address has valid syntax, whether the domain has resolvable DNS MX records (confirming it can receive mail), and whether the domain is identified as a known disposable/temporary email provider.
Example use cases
Block disposable emails at signup
“A user just signed up with the email throwaway123@guerrillamail.com — can you check if that's a disposable or fake email address so I can decide whether to allow the registration?”
Pre-send deliverability check
“Before I send a newsletter to newsletter-list@mybusiness.net, can you verify the email has valid MX records and isn't going to bounce?”
Validate user-submitted contact email
“Someone submitted support@unknowndomain.xyz as their contact email on our form — can you check if the syntax is valid and if that domain actually has mail servers set up?”
Technical details
Endpoint
POSThttps://amanchain-relay.gitajhd.workers.dev/api/x402/aman-email-validateWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call email validation that covers syntax, DNS MX reachability, and disposable-domain detection without requiring an API key or account setup. Ideal for agent workflows that need to screen individual email addresses at the point of user input, form submission, or lead capture, especially when integrated with x402 micropayment flows on Base.
Side effects
- Malformed input JSON returns an error with missing field indication
- DNS lookup timeout may occur for very slow or non-existent domains
- Disposable email database may not include very new throwaway domains
- Invalid or missing serviceId field causes request rejection
- Network errors or AmanChain node unavailability return a service error
