Domain Info API

The domainAPI info API enables you to rapidly retrieve data related to the hosted web page of a specific domain.

Such information include traffic, historical traffic data, traffic ranking including country specific ranking, displayed name, average load time, related sub-domain, linked websites… and more information essential when analyzing a domain name in term of its past or current usage and potential.

As for now the main source of data for this API is Alexa. We will enhance this API by adding additional sources.
