Anyone can obtain an API Key and use the APIs free of
charge, provided that our policies for using APIs and the data are
honored. Furthermore, full API access is only granted to clients
that run within the networks of organizations that have
subscriptions to the corresponding Elsevier product. Clients
without subscriptions have access to limited basic metadata for
most publications and citation records, as well as to basic search
functionality. Content published by Elsevier under Open Access
licenses is fully available.
APIs are also available for OAuth authentication; for
electronic holdings exchange in KBART format and for checking a
user's access rights for specific publications. These APIs are
made available to customers and partners upon request, subject to
approval.
