Overview
The DomainTools API is organized into distinct products with queries that follow a RESTful URL structure wherever possible. Each product offers free, un-authenticated access for the sample URLs listed with each product. If you haven’t already, you may want to review the getting started document to learn about authentication and response formats.
The Reverse MX API provides a list of Domains, MX records, and SPF records related to your search. Specify the search type by using only one of the allowed parameters.
