Web of Science client using API v3.

Project description


travis readthedocs license version downloads stars

Web of Science (previously Web of Knowledge) is an online subscription-based scientific citation indexing service maintained by Clarivate.

wos is a python SOAP Client (both API and command-line tool) to query the WOS database in order to get XML data from a query using the WWS access.


The package has been uploaded to PyPI, so you can install the package using pip:

pip install wos


This README and the documentation for the classes and methods can be accessed on ReadTheDocs.


You can use the wos command to query the Web of Science API. If you want to access data that needs to be accessed using the premium API, you also have to authenticate using your username and password.

usage: wos [-h] [–close] [-l] [-u USER] [-p PASSWORD] [-s SID]

{query,doi,connect} …

Query the Web of Science.

positional arguments:
{query,doi,connect} sub-command help

query query the Web of Science. doi get the WOS ID from the DOI. connect connect and get an SID.

optional arguments:
-h, --help

show this help message and exit


Close session.

--proxy PROXY

HTTP proxy

--timeout TIMEOUT

API timeout

-l, --lite

Wos Lite

-v, --verbose



API credentials for premium access.

-u USER, –user USER -p PASSWORD, –password PASSWORD -s SID, –sid SID

You can use the WOS Lite API using the --lite parameter (for each query).

You can also authenticate using the session id (SID). In fact the sessions are not closed by the command line utility. Example:

$ wos --user JohnDoe --password 12345 connect
Authenticated using SID: ABCDEFGHIJKLM

$ wos --sid ABCDEFGHIJKLM query 'AU=Knuth Donald' -c1
Authenticated using SID: ABCDEFGHIJKLM
<?xml version="1.0" ?>

                    <WUID coll_id="WOS"/>
                    <edition value="WOS.SCI"/>

                          sortdate="2011-03-01" vol="33">
                    <page begin="33" end="45" page_count="13">33-45</page>
                <titles count="6">
                    <title type="source">MATHEMATICAL INTELLIGENCER</title>

$ wos --sid ABCDEFGHIJKLM doi '10.1007/s00283-010-9170-7'

Check the user_query documentation to understand how to create query strings.


Obviously you can also use the python client programmatically:

from wos import WosClient
import wos.utils

with WosClient('JohnDoe', '12345') as client:
    print(wos.utils.query(client, 'AU=Knuth Donald'))


In wos 0.1.11+, the WosClient class can access the following APIs.

[FAQ] I cannot connect …

I am not affiliated with Clarivate. The library leverages the Web of Science WWS API (Web Services Premium or Lite), which is a paid service offered by Clarivate. This means that your institution has to pay for the Web of Science Core Collection access. The simple registration to Web of Knowledge / Web of Science does not entitle you to access the WWS API service.

So if you receive errors like No matches returned for Username or No matches returned for IP, these errors are thrown directly by the WWS API server. This means that the library is correctly communicating with the server, but you do not have access to the Web Services API. I do understand that you can access the WOS website from your network, but the website access and the API access (used in this project) are two separated products, and the website access does not imply the API access, since Clarivate bills them separately. This project does not scrape the website (which would violate the terms of usage) but invokes the WWS APIs offered by Clarivate. Thus there is nothing this project can do to help you.

If you think this is an error and you should be entitled to access the services, please contact Clarivate support first and verify if you have the WWS access. Please open an issue ONLY when you have (1) verified with Clarivate support that you have WWS access; (2) verified that you are connected from the correct network.
