How this service works
Validate email format, disposable-domain heuristics, and live DNS MX records via DoH for outreach and lead-gen agents
Output
Returns a JSON object with: ok (overall validity boolean), valid_format (format check boolean), has_mx (whether MX records exist), mx (array of MX records from DoH lookup), email (normalized input), and service (domain label or disposable-service name if detected).
Example use cases
Example prompt
“Can you validate whether john.doe@example.com is a real, deliverable email — check the format, whether it's a throwaway domain, and whether the domain actually has MX records set up?”
Technical details
Endpoint
GEThttps://vending-machine-seven.vercel.app/api/v/email-validateWhen to prefer
Use this endpoint when you need a three-layer email check (syntax + disposable-domain heuristics + live DNS MX verification) in a single call, especially for outreach pipelines, lead-gen agents, or CRM ingestion flows where deliverability and hygiene matter. Prefer over pure format-only validators when you need live DNS confirmation that the domain can actually receive mail.
Side effects
- Missing email query param — returns 400 or validation error
- Invalid or unparseable email format — ok: false, valid_format: false
- Domain has no MX records — has_mx: false, mx: []
- DoH lookup timeout or DNS resolution failure — may return partial result or error
- Disposable domain detected — reflected in service field and ok flag
