Your first 5 minutes with the Majestic API

This page is designed for the standard API authorisation available on Platinum (Legacy) and API plans. If you wish to write an OpenApps application, we suggest you start with this guide, and then progress to the OpenApps specific documentation.

For in depth technical detail about the API, please visit the API reference page.


The Majestic API is available on two endpoints – a Developer API with an older, limited version of our index intended for development, and an Enterprise API which uses the resources on your subscription to query our live data sets.

Our website accesses our Fresh and Historic Indexes in a very similar manner to the public API. We therefore suggest familiarising yourself with the website to assist development and help support personnel to deal with any of your queries.

How are requests made?

Our API is based on HTTP. An HTTP GET or POST request is sent from your application to one of the two endpoints discussed above. This endpoint returns a response synchronously. For some commands, you may be required to make further HTTP requests to download the data requested.

What does a response looks like?

Following your HTTP GET or POST request, our server will return a response in either XML or JSON. Our JSON format is more humanly readable, but comes at the cost of bandwidth. We therefore advise users to maximise performance by using XML.

Example XML and JSON responses to the GetIndexItemInfo call, which is the fastest way to get statistics on one or more domains, are shown below.

This query in the Fresh Index produces the following XML:
