Yes, Denodo can access Cloud API as a data source in the form of REST or SOAP web services exposed by the Cloud API. You can create a JSON/XML data source in Denodo platform to use a REST Web service. Please refer to the section, [JSON sources](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/creating_data_sources_and_base_views/json_sources/json_sources) of the VDP Admin guide for more information on creating JSON data sources and the section [XML sources](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/creating_data_sources_and_base_views/xml_sources/xml_sources) for more information on creating XML data sources.
Similarly, to use a SOAP webservice, you can create a web service data source. Please refer to the section, [Web service sources](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/creating_data_sources_and_base_views/soap_web_service_sources/soap_web_service_sources) for more information on creating a data source that points to a SOAP web service.
Hope this helps!
