How this service works
50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.
Output
Returns a JSON object with three boolean fields: 'valid' (whether the email is syntactically correct), 'mx' (whether the domain has valid MX records indicating it can receive email), and 'disposable' (whether the address belongs to a known temporary or throwaway email provider).
Example use cases
Signup form fraud prevention
“Before I add this user to my database, check whether the email they submitted — tempuser@mailinator.com — is a disposable or fake address so I can decide whether to block the registration.”
Lead list quality check
“I have a potential sales lead with the email contact@acmecorp.io — can you verify it's a real email with a working mail server before I add them to my outreach campaign?”
Newsletter subscriber validation
“Someone just subscribed to my newsletter with the address test123@guerrillamail.com — is that a valid, non-throwaway email address I should accept?”
Technical details
Endpoint
GEThttps://skinwinking.com/api/v1/web/email-validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use email validation check that covers syntax, MX record existence, and disposable email detection in a single call. Ideal for agents that need to validate individual email addresses at the point of collection without maintaining an in-house validation service. At $0.001 USDC per call it is cost-effective for sporadic or moderate-volume checks. Prefer a dedicated bulk email verification service if processing thousands of addresses in a batch.
Side effects
- Missing 'email' query parameter returns an error
- Malformed email string may return valid:false with no MX check
- Unresolvable domain may return mx:false
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Transient DNS lookup failures may produce incorrect mx results
