How this service works
Classify an email address by its domain: company vs. known free provider (Gmail/Outlook/…) vs. disposable domain. List-based heuristic, not a live DNS/MX check.
Output
Returns a JSON object with the inferred entity type (e.g. 'company'), the extracted domain (e.g. 'acmecorp.com'), a confidence score between 0 and 1, a boolean indicating whether the domain is a disposable email service, and a boolean indicating whether it is a free email provider.
Example use cases
Example prompt
“Can you check whether the email john.smith@acmecorp.com belongs to a real company domain, and tell me if it's disposable or a free provider like Gmail?”
