How this service works
Validate an email address: format check, MX record lookup, disposable domain detection. Pass ?email= query param.
Output
Returns a JSON object with: valid (overall validity), formatOk (syntax check), hasMX (whether domain has mail exchange records), isDisposable (disposable domain flag), domain, mxProviders list, reason for invalidity if any, a suggested correction if applicable, and a checkedAt timestamp.
Example use cases
Example prompt
“Can you check if the email address 'user@somedomain.com' is valid — like whether the format is correct, if the domain actually has mail servers, and if it's a throwaway disposable address?”
Technical details
Endpoint
POSThttps://httpay.xyz/api/email-validateWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call email validation that combines format checking, live MX record DNS lookup, and disposable domain detection in a single call with no API key or subscription required. Ideal for AI agents that need to validate email addresses infrequently or on-demand via x402 micropayments on Base.
Side effects
- Missing email parameter returns error
- Malformed email string may yield formatOk:false with reason explaining the syntax issue
- DNS lookup failure may cause hasMX to return false even for valid domains
- Disposable domain list may not be exhaustive, causing false negatives for newer burner services
- Network timeout on MX lookup may delay response
