How this service works
Email validation: syntax, domain MX records and disposable-domain flag. Sends no email; the address is not stored.
Output
Returns a JSON object with: whether the email is overall valid (valido), whether the format is syntactically correct (formato_valido), whether the domain has a mail server (tiene_servidor_correo), the list of MX servers (servidores_mx), the domain portion (dominio), whether the domain is disposable/throwaway (desechable), the original email (email), and an optional note (nota).
Example use cases
Screen signups for disposable emails
“Before I add this new user to my mailing list, check if 'user123@guerrillamail.com' is a disposable or temporary email address and whether the domain even has mail servers.”
Validate bulk-imported contact email
“I just imported a contact with the email 'marketing@acmecorp.co' — can you verify that the address has valid syntax, the domain has MX records, and it's not a throwaway address?”
Pre-send email hygiene check
“Before my app sends a welcome email to 'newuser@yopmail.com', can you confirm whether that address is deliverable and flag it if it's from a disposable email provider?”
Technical details
Endpoint
POSThttps://api.vextorium.com/validar-email-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need lightweight, privacy-safe email validation that checks syntax, domain deliverability (MX records), and disposable-domain detection — all in a single call, without sending any email or storing the address. Prefer it over full email verification services that send confirmation messages, or over local regex checks that miss MX and disposable-domain signals.
Side effects
- Missing or malformed email field returns an error response
- Non-existent domain with no DNS record may cause lookup failure or return tiene_servidor_correo=false
- Ambiguous or punycode international domains may not resolve correctly
- Network timeouts during MX lookup may cause slow or failed responses
- Unusual TLDs may not be recognized as disposable even if they are
