Has anyone successfully created a visual page using Apex/CURL programming to create ORCID ID on http//:orcid.org?

I am new to Salesforce platform.  Not sure if it is possible to run CURL command on the Salesforce platform using APEX programming lanugage to retrieve external data source from another website such as ORCID ID from www.Orcid.org website.  Although I have successfully retrieved data from Salesforce object by running CURL command on my Windows 7 based computer.
If it is possible, can you please point me to information on how to run simple CURL command on the Salesforce platform.
Thanks
