stormap.ai/x402/v1/email_domain_check

Use when an email address or domain needs a legitimacy check, for signup screening, lead research or list cleaning. Returns looks_legitimate, risky or invalid with reasons: syntax, role address, disposable or free provider, MX or null MX, mail provider, SPF, DMARC policy, website live and domain age from RDAP. Does not contact the mail server, so a specific mailbox is not confirmed. Errors: 400 bad_input. Failed calls are not charged.
