Welcome to the LexisNexis® Web Services Kit
LexisNexis® Research Services enable you to find critical information
from reliable sources quickly, including records and news on legal, business,
financial, political, and industrial subjects. We provide fast access to
millions of documents, many dating back for decades, and others that are just
being published today. Moreover, the LexisNexis reputation for accuracy
means that documents retrieved through our service are considered reliable
throughout the legal and business world.
This LexisNexis® Web Services Kit gives your developers tools to
customize the way your people search our databases, including the abilty to:
The illustration below shows an effective implementation of this Web Services
Your company's employee running your Customer
Application requests a search.
Using your customizations, the Web Services Kit reformats the search for
access to the LexisNexis® library of sources.
That information is transmitted back to your systems in XML formats that
you can manipulate for display, printing, and use in follow-up requests.
The retrieved information may include summaries of sources as well as
tables of contents and other information to assist in follow-up requests.
The Web Services Kit API (Application Programming Interface) allows
your developers to incorporate our most popular research capabilities into your
own online research application(s) with minimal coding effort.
Your developers will:
- Design the mechanism used to request information.
- Control how requests are packaged for sending to the Web Services Kit
- Control how the XML information that is retrieved will be reformatted
for presenting to the user.
By using a Web Services development tool that supports the Web Service Description Language (WSDL), you can use the provided WSDL files to build valid message structures and even handle the message exchanges between your system and LexisNexis.
Implementing a Customized Online Research Application
To help you use the LexisNexis Web Services Kit to design and deliver the
solution you need, LexisNexis will help you form a project team to oversee the
following four phases of the project:
The Implementation Process page describes this process
and related features in more detail.

- Compliance -- We review your completed application for
search effectiveness, system efficiency, and appropriate LexisNexis branding.
