Keyword Discovery - FREE API manual

Click here to access the manual for the Full function API option as part of the Enterprise subscription.

The Keyword Research API (Application Programming Interface) provides a set of query functions to the Keyword Research database. The API can be integrated into custom applications or used as an alternative interface.

The API provides functions for retrieving data on single keywords, multiple keywords from a single query and account status checking. The queries return all data in XML format and the functions accept parameters as GET or POST values.

NOTE: The option between single and multiple queries has to be activated by admin, member will not be able to change the type of query results by modifying URL parameters. Contact us to change the results type for your account.

For more information on how to implement the KeywordDiscovery API in your applications using programming languages, see actual PHP, Perl and C#.Net code examples.

Authentication - No Longer Offered


Authentication for the API system is performed using standard HTTP authentication. When sending a query via the API using a webbrowser a message box will appear, requiring the account holder's username and password to be entered in order to continue.

Authentication details can also be sent via the URL by inserting the username and password separated by a colon and suffixed with @, before the hostname in the query URL.

NOTE: Remember that data supplied via URL's should be correctly URL encoded.

NOTE: Microsoft Internet Explorer has disabled the ability to supply usernames and passwords via the URL in the latest versions.
This will stop you from testing this in Internet Explorer.

An example of checking the account status showing the URL authentication method:

username: user@host.com
password: secret

http://user%40host%2Ecom:secret@api.keyworddiscovery.com/top15.php

Any authentication failure will return a HTTP 401: Unauthorized.
