How this service works
Pay-per-call utility APIs for AI agents, settled in USDC via the x402 protocol.
Output
Returns a JSON object containing the original email, parsed local part and domain, whether MX records were found and their details, syntax validity, whether it's a disposable address, whether it's from a free email provider, and a deliverability hint indicating if the address is likely to accept mail.
Example use cases
Example prompt
“Can you check whether user@gmail.com is a real, deliverable email address — tell me if it has valid MX records, whether it's disposable, and if it's from a free provider?”
Technical details
Endpoint
POSThttps://x402.nichospt.net/email-validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call email validation check with MX record lookup, disposable email detection, and deliverability hints — especially in agent workflows where you only pay for what you use and need real-time validation without a subscription. Prefer this over form-only regex validation when deliverability and disposable detection matter.
Side effects
- Missing or malformed email input returns a validation error
- Non-existent domain may return mx_found: false and deliverable_hint: false
- Payment failure via x402 protocol results in 402 response before processing
- Rate limiting or service unavailability returns 5xx errors
- Temporary DNS lookup failures may produce inconclusive MX results
