Duda makes multi-screen websites for desktop, tablet and mobile. The site takes existing content from the web and churns a website optimized for all devices, usually completed in minutes. Duda API allows users to: Create Sites, Create Sub-Accounts*, Sign users into the account (via SSO), Access Site Analytics, and pull an updated list of supported mobile user agents. The Duda API allows users to integrate these options into third-party platforms, instead of having to log into Duda directly. The API uses REST calls and returns JSON. The service is free to use, but an account is required with service.
