How this service works
Pay-per-call email validation via x402 (USDC on Base): syntax, MX lookup, SMTP deliverability, disposable / role-account / free-provider flags, typo suggestions, and a 0-1 confidence score.
Output
For each email address submitted, the endpoint returns: syntax validity, MX record lookup result, SMTP deliverability check, boolean flags for disposable/role-account/free-provider classification, a typo suggestion if applicable, and a 0-1 confidence score indicating overall deliverability confidence.
Example use cases
Pre-send campaign list cleanup
“I have a list of email addresses collected from our sign-up form — can you check all of them for deliverability, flag any disposable or role-based ones like info@ or noreply@, and give me a confidence score so I know which ones are safe to include in our next campaign?”
Typo correction at registration
“A user just signed up with the email james.wilson@gmial.com — can you validate it, tell me if it's deliverable, and suggest the correct spelling if there's a typo?”
CRM import quality gate
“Before I import this batch of contacts into our CRM, can you validate all their emails, flag any that are from free providers or look like throwaway addresses, and give me a confidence score for each so I can decide which ones to keep?”
Technical details
Endpoint
GEThttps://validate.cyberwarex.com/validate-batchWhen to prefer
Choose this endpoint when you need multi-dimensional email validation beyond simple syntax checking — especially when you need MX lookup, SMTP deliverability confirmation, disposable/role/free-provider detection, typo suggestions, and a machine-readable confidence score all in one call. Prefer it for pre-send list hygiene, CRM import gating, or real-time sign-up validation where bad email quality has a direct cost. The pay-per-call USDC pricing via x402 makes it suitable for sporadic or agent-driven workflows without subscription overhead.
Side effects
- Payment not provided or invalid x402 USDC payment — returns 402 Payment Required
- Malformed or missing 'emails' query parameter — returns 400 Bad Request
- Email string unparseable — validation may return syntax-failed result
- SMTP check timeout for slow mail servers — deliverability result may be inconclusive
- Temporary network issues reaching remote MX servers — reduced confidence score with partial results
