API Integrations
All OpenSRS Reseller accounts include full access to the OpenSRS API. It's a powerful set of integration tools that enable the sale and management of domain names, DNS, email services and SSL certificates.
Domains API
The OpenSRS API includes a number of powerful features that enable Resellers to offer a substantially better domain search experience to their customers. The OpenSRS API includes the ability to lookup domains across all top-level domains as well as name suggestions (in multiple languages) powered by Domains Bot at no additional charge. The API also returns results from the domain name aftermarket through partnerships with leading aftermarket domain portfolio holders.
Thanks to free managed DNS included with every domain name sold (where applicable), all aspects of DNS can be performed via the OpenSRS API for a complete end-to-end integration.
SSL Certificates API
Using the OpenSRS API, you can provision and manage SSL certificates from the world's leading brands.
Hosted Email and Email Filtering API
OpenSRS Email Service includes a full API that allows you to provision and manage all aspects of the email service including the creation and deletion of email domains and individual email accounts, management of user passwords, and other email service functions.
