Yes and no, the EWP Network is completely free. But there are indirect costs. Implementing the EWP APIs (connectors) to the database software of an institution will require technical ICT development since most software at HEIs needs to be made ready for data exchange outside their own servers. Usually, this means the interface has to be changed as well. It is therefore imperative that HEIs start up this ICT development urgently.
If you use third-party tools, it is your provider who will make the connection. In principle, no extra money can be charged for the use of a module that allows exchanges through the EWP Network.
Finally, the EWP Dashboard is a completely free tool for interinstitutional agreements and learning agreements management among other functionalities.
