Webmaster API
The Webmaster API provides access to Yandex.Webmaster site data. The API is useful for hosting providers and developers of CMS or web analytics tools. For example, you can show information about indexed pages and traffic right in the hosting control panel. Or let your clients submit a site for indexing immediately after creating it and easily verify site management rights.
