How this service works
Verify an email address: syntax check, domain MX lookup, disposable-domain and role-account flags. Use before sending or storing an address.
Output
Returns structured flags for the queried email address: whether the syntax is valid, whether the domain has valid MX records (indicating deliverability), whether the domain is a known disposable/temporary email provider, and whether the address is a role account (e.g. info@, support@, noreply@).
Example use cases
Block fake signups at registration
“A user just tried to sign up with the email throwaway99@guerrillamail.com — can you check whether it's a disposable or fake address before I let them create an account?”
Scrub email list before campaign
“I'm about to send a newsletter to a list of collected addresses. Can you check whether contact@example.org is a valid deliverable email or a role account I should skip?”
Validate lead before CRM entry
“I've got a new sales lead who gave me the email noreply@bigcorp.com — can you verify whether that's a real person's inbox or a role account I shouldn't bother cold-emailing?”
Technical details
Endpoint
GEThttps://agentrxi.com/v1/email/verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, fast, multi-signal email check — syntax, MX, disposable, and role-account — in a single pay-per-call API with no subscription. Ideal for agents that encounter user-submitted emails at runtime (signups, CRM entry, campaign lists) and need a quick go/no-go signal without setting up a dedicated email validation service.
Side effects
- Missing or malformed email parameter returns a 400-style error
- Domain has no MX records — deliverability check fails but syntax may still pass
- Disposable domain list may not include every new throwaway provider
- Rate limiting or payment failure (402) if USDC balance is insufficient
- Legitimate domains occasionally misidentified as disposable due to shared infrastructure
