Web of Science Expanded API

The modifiedTimeSpan parameter can now be applied to the /citing endpoint. This parameter does not work with the ‘all databases’ search (databaseId=WOK). Applying modifiedTimeSpan with databaseId=WOK now returns an error on all endpoints.

Web of Science Starter API

The API now supports the ‘sourceURL’ search tag, abbreviated as SUR. This extends the Starter API functionality to support a Data Citation Index (DRCI) search option previously available on the deprecated Links AMR API.

A new ‘detail’ parameter is now available. This new parameter allows the user to choose between receiving the full response data (detail=full), or an abbreviated version (detail=short) that closely matches the data previously available through Links AMR.

Links AMR

To alert users of the impending sunset of Links AMR, the API will experience a series of scheduled ‘brownouts’ where the API will respond with an error message instead of data.

Web of Science Starter API

A new optional parameter has been added to the Starter API: modifiedTimeSpan. The parameter allows a user to search only for documents modified during a certain time space, limiting results to those with only the most recent updates. This will be especially useful for data integration projects where the application makes regular API calls to check for updated data in WoS.
