The AuthorityLabs Interface API allows you to interact with AuthorityLabs' tracked domains and keywords. The API requires that you provide an API key as a custom HTTP header. It is in beta and is subject to change. AuthorityLabs provides this API to gain access to Raw HTML, Real-time Results, JSON SERPs and more. It provides a way to get the top 100 results for each keyword assembled and parsed into JSON. AuthorityLabs provides simple and scalable search engine rank monitoring software to track and analyze performance for Google, Yahoo!, and Bing.
