Clients pin an API version per API key (editable in the dashboard) or per request via the Nevermined-Version header; the platform reshapes requests and responses so every supported pin keeps working. See the versioning guide.
  • Floor (oldest supported version): 1.0
  • Live current version: GET /api/v1/meta/versions
