Is there a web service that retrieves all of the ORCIDs for the authors associated with a DOI? I've looked at crossref.org, but I can't seem to find information on how to do this with their service.
I am currently using their HTTP-based API to query information about a publication given its DOI. It returns the names of the authors, but not their ORCIDs.
(An ORCID (Open Researcher and Contributor ID) is a unique identifier for an author of a publication. A DOI (Digital Object Identifier) is the same thing, but for the publication itself)
