Web of Science Web Services are SOAP-based APIs to access and search Web of Science database subscription content. The web services can be used on any platform that can perform an HTTPS POST request and receive and process XML data, including PHP, Java, C#, .Net, C++ and some mobile platforms.

Web of Science Web Services consist of two JAX-WS web services:

  • WOKMWSAuthenticate
  • WokSearch

WOKMWSAuthenticate is an authentication and session management service. WokSearch is a data retrieval service.

Web of Science Web Services are session-based: the services have state. The services retain your authentication information, service entitlements, and the queries that you have run during a single session.
